What brings people here
These are the concerns most often raised at a longevity assessment. Many of them are easy to normalise, or to put down to age and a busy life. Most have contributors that can be measured. This page sets out what each may relate to, and which measurements help make it clearer.
Energy and sleep
Persistent tiredness is the single most common reason people seek a longevity assessment, and it is rarely explained by one thing alone. Sleep quality, thyroid function, iron and vitamin D status, blood sugar regulation and chronic inflammation all feed into how much energy you have. Because these interact, measuring them together usually explains more than investigating any one in isolation.
Fatigue
Ongoing tiredness that rest does not resolve. May relate to sleep quality, thyroid function, iron status, blood sugar regulation or inflammation.
Programme Micronutrient optimisation · Iron therapy · Metabolic optimisation
Low energy
A general drop in day-to-day capacity. Often assessed alongside metabolic markers, nutrient status and recovery data.
Programme Micronutrient optimisation · Metabolic optimisation
Poor sleep
Difficulty falling asleep, staying asleep, or waking unrefreshed. Sleep regularity predicts long-term health outcomes more strongly than duration alone.
Programme Sleep optimisation
Daytime sleepiness
Struggling to stay alert during the day. Can reflect sleep quality, breathing during sleep, or blood glucose fluctuation.
Programme Sleep optimisation
Snoring or sleep apnoea
Disrupted breathing during sleep. Associated with cardiovascular and metabolic risk, and often under-recognised.
Programme Sleep optimisation
Poor recovery after exercise
Taking longer to bounce back than expected. Often assessed through heart rate variability trends, inflammation and nutrient status.
Programme Recovery optimisation
Typically assessed with Metabolic panel, thyroid and hormone health, iron studies, micronutrient profiling, inflammation profiling, wearable sleep data
Mind and mood
Cognitive and mood concerns are frequently dismissed as stress or ageing, yet they often have measurable contributors. Sleep debt, blood glucose instability, thyroid function, vitamin D and B12 status, and chronic inflammation all influence how clearly you think and how steady you feel. Assessing these does not replace mental health care, but it can identify physical factors that are worth addressing alongside it.
Brain fog
Difficulty concentrating or thinking clearly. Commonly assessed alongside sleep, blood glucose stability, thyroid function and nutrient status.
Programme Cognitive health
Poor memory or forgetfulness
Noticing lapses more often than before. A cognitive baseline makes subtle changes trackable rather than guessed at.
Programme Cognitive health
Cognitive decline
A perceived change in mental sharpness over time. Baselining early makes it possible to monitor rather than react.
Programme Cognitive health
Chronic stress or feeling overstretched
Sustained demand without adequate recovery. Can flatten the normal daily cortisol rhythm and affect sleep, weight and glucose handling.
Programme Stress management
Burnout
Exhaustion accompanied by reduced capacity and detachment. Often overlaps with disrupted cortisol patterns and poor sleep quality.
Programme Stress management · Recovery optimisation
Irritability
A shorter fuse than usual. May relate to sleep debt, blood glucose swings or hormonal change.
Programme Stress management
Mood swings
Fluctuations in mood across a day or month. Often assessed alongside thyroid, sex hormones and blood glucose stability.
Programme Stress management
Anxiety
Persistent worry or physical tension. Physical contributors such as thyroid function can be assessed, alongside appropriate mental health support.
Programme Stress management
Depression
Low mood, loss of interest or motivation persisting over time. This warrants proper mental health care; physical contributors can be assessed in parallel.
Programme Stress management
Typically assessed with Cognitive assessment, thyroid and hormone health, micronutrient profiling, inflammation profiling, metabolic panel
Weight and metabolism
Weight is the visible part of a mostly invisible system. What matters clinically is where fat is stored and how well your body handles glucose, not what a scale reads. Insulin resistance can develop for years while fasting glucose stays normal, which is why fasting insulin, HOMA-IR and direct body composition give a much earlier picture than weight and BMI alone.
Weight gain
Gaining weight without a clear change in habits. Often reflects insulin sensitivity, sleep, stress physiology or thyroid function.
Programme Medical weight management · Metabolic optimisation · Visceral fat reduction
Belly fat or visceral fat
Fat carried around the abdomen. More closely linked to metabolic and cardiovascular risk than fat stored under the skin.
Programme Medical weight management · Visceral fat reduction
Difficulty losing weight
Effort not translating into results. Worth assessing metabolic rate, insulin sensitivity, thyroid function and muscle mass together.
Programme Medical weight management · Metabolic optimisation
Insulin resistance
Cells responding less effectively to insulin. Often present for years before blood glucose becomes abnormal.
Programme Medical weight management · Metabolic optimisation
Prediabetes
Blood glucose above normal but below the diabetes threshold. Substantially modifiable when identified early.
Programme Medical weight management · Metabolic optimisation
High blood sugar
Elevated glucose on testing. Best interpreted alongside fasting insulin and HbA1c rather than in isolation.
Programme Medical weight management · Metabolic optimisation
Slow metabolism
A sense that the body burns less than it used to. Resting metabolic rate can be measured rather than assumed.
Programme Medical weight management · Metabolic optimisation
Sugar cravings
Frequent urges for sweet or refined food. Often tracks with blood glucose instability and sleep debt.
Programme Medical weight management · Metabolic optimisation
Emotional eating
Eating in response to stress or mood rather than hunger. Addressed with dietitian support alongside metabolic assessment.
Programme Medical weight management · Metabolic optimisation
Fatty liver
Fat accumulation in the liver. Common, frequently silent, and closely tied to insulin resistance and visceral fat.
Programme Medical weight management · Fatty liver management · Liver health
Typically assessed with Metabolic panel, fasting insulin and HOMA-IR, 3D body composition, visceral fat mapping, resting metabolic rate, liver assessment
Heart and circulation
Cardiovascular risk builds silently across decades, and a standard lipid panel does not capture all of it. ApoB counts the particles that actually enter the arterial wall, while Lp(a) is largely inherited, elevated in roughly one in five people, and absent from most routine tests. Measuring both gives a far more complete picture than cholesterol alone.
High cholesterol
Raised lipids on testing. ApoB and Lp(a) add meaningful detail that a standard panel does not provide.
Programme Metabolic optimisation
High blood pressure
Elevated readings over time. A major modifiable contributor to long-term cardiovascular and cognitive risk.
Programme Metabolic optimisation
Typically assessed with Cardiometabolic risk panel, advanced lipid markers including ApoB and Lp(a), inflammation profiling, blood pressure assessment
Hormonal and sexual health
Hormonal change affects energy, mood, body composition, sleep and intimacy, and it is often endured rather than assessed. These concerns are common, they are clinical rather than embarrassing, and most are measurable. Thyroid function, sex hormones and metabolic markers are usually assessed together, because they influence one another.
Hormonal imbalance
A sense that hormones are not settled. Best approached by measuring the relevant panels rather than inferring from symptoms alone.
Programme Postmenopausal health · Andropause
Thyroid symptoms
Fatigue, weight change, temperature sensitivity or hair changes. Thyroid function is straightforward to assess.
Programme Metabolic optimisation
Low testosterone
Reduced energy, drive, muscle mass or mood in men. Measurable, and interpreted alongside metabolic markers.
Programme Andropause
Loss of sex drive
Reduced interest in intimacy. Can relate to hormones, sleep, stress physiology, medication or relationship context.
Programme Andropause · Postmenopausal health
Erectile dysfunction
Often an early signal of vascular or metabolic change, which is why it is worth assessing rather than ignoring.
Programme Andropause · Metabolic optimisation
Low libido in women
Reduced desire, which may relate to hormonal change, sleep, stress or life stage.
Programme Postmenopausal health
Menopause symptoms
The cluster of changes around the menopausal transition. Assessment supports informed decisions about management.
Programme Postmenopausal health
Hot flushes
Sudden warmth, flushing or night sweats, commonly associated with hormonal transition.
Programme Postmenopausal health
Vaginal dryness
A common and treatable consequence of hormonal change, often unreported.
Programme Postmenopausal health
Painful intercourse
Discomfort during sex. Worth raising clinically; frequently related to hormonal change and manageable.
Programme Postmenopausal health
Irregular periods
Changes in cycle length or pattern. May relate to hormonal, thyroid or metabolic factors.
Programme Postmenopausal health
PCOS symptoms
Features that may include irregular cycles, skin or hair changes and weight difficulty, often alongside insulin resistance.
Programme Metabolic optimisation
Urinary incontinence
Loss of bladder control. Common, under-discussed, and often improvable with the right assessment.
Programme Postmenopausal health
Typically assessed with Hormone health panel, thyroid assessment, metabolic panel, body composition, micronutrient profiling
Muscle, bone and joints
Muscle is not cosmetic tissue. It is your largest site of glucose disposal, your reserve during illness, and the structural difference between independence and dependence in later decades. Muscle mass begins declining from the fourth decade, quietly, which is why measuring strength and body composition matters long before frailty is a concern.
Loss of fitness
Reduced capacity for activity you used to manage. Cardiorespiratory fitness is measurable and highly trainable at any age.
Programme Recovery optimisation · Muscle mass growth
Muscle loss (sarcopenia)
Progressive loss of muscle mass and strength with age. Measurable, and responsive to resistance training and adequate protein.
Programme Muscle mass growth · Frailty prevention
Difficulty building muscle
Training without the expected response. Worth assessing protein intake, hormones, recovery and inflammation.
Programme Muscle mass growth
Joint pain
Discomfort in one or more joints. Often assessed alongside inflammation, body composition and movement quality.
Programme Pain management
Aches and pains
Generalised discomfort. May relate to inflammation, nutrient status, activity patterns or recovery.
Programme Pain management
Osteoporosis risk
Concern about bone density, particularly after menopause or with a family history. Modifiable through loading, nutrition and hormonal health.
Programme Osteoporosis prevention
Typically assessed with 3D body composition, muscle quality and posture analysis, grip strength, micronutrient profiling, inflammation profiling
Skin and hair
Skin and hair are visible reflections of internal processes. Thyroid function, iron and vitamin D status, blood glucose regulation, hormonal change and inflammation all show up externally, often before they are noticed elsewhere. Assessment can identify contributors that topical treatment alone will not resolve.
Hair loss
Thinning or shedding. Commonly assessed alongside thyroid function, iron status, hormones and nutrient adequacy.
Programme Iron therapy · Micronutrient optimisation
Dry skin
Persistent dryness. May relate to thyroid function, nutrient status or hydration and barrier health.
Programme Micronutrient optimisation
Wrinkles or sagging
Changes in skin firmness and elasticity. Influenced by sun exposure, glycation, collagen turnover and hormonal status.
Skin discolouration
Uneven tone or pigmentation. Assessed dermatologically, with metabolic and hormonal contributors considered.
Premature ageing
A sense of ageing faster than your years. Biological age and pace-of-ageing measures make this assessable rather than subjective.
Programme Biohacking programme · Metabolic optimisation
Typically assessed with Thyroid and hormone health, iron studies, micronutrient profiling, inflammation profiling, metabolic panel
Digestion and gut
The gut influences far more than digestion, with links to immune regulation, inflammation, mood and nutrient absorption. Symptoms that are easy to normalise, such as bloating or reflux, are worth assessing properly, because persistent digestive issues can affect how well the rest of the body is nourished.
Bloating
Abdominal fullness or distension. May relate to food tolerance, gut function or eating patterns.
Programme Gut microbiome programme
Constipation
Infrequent or difficult bowel movements. Often responsive to fibre, hydration, movement and gut assessment.
Programme Gut microbiome programme
Acid reflux (GERD)
Regurgitation or burning discomfort. Worth assessing rather than managing indefinitely with over-the-counter relief.
Programme Gut microbiome programme
Poor gut health
A general sense that digestion is not right. Assessed alongside diet, intolerances and inflammation.
Programme Gut microbiome programme
Food intolerance
Symptoms following particular foods. Testing can distinguish intolerance from allergy and guide dietary planning.
Programme Gut microbiome programme
Typically assessed with Gut health assessment, food intolerance and allergy testing, micronutrient profiling, inflammation profiling, dietitian consultation
Immunity and inflammation
Chronic low-grade inflammation, sometimes called inflammaging, sits beneath a wide range of age-related conditions. Unlike the acute inflammation that follows injury, it persists quietly for years and is measurable through markers such as high-sensitivity CRP. Frequent illness and allergy are worth assessing alongside it.
Chronic inflammation
Persistent low-grade inflammation. Measurable, and associated with cardiovascular, metabolic and cognitive risk.
Programme Metabolic optimisation · Gut microbiome programme
Frequent illness
Catching infections more often than expected. Worth assessing nutrient status, sleep, stress load and inflammation.
Programme Micronutrient optimisation
Low immunity
A sense of reduced resilience. Assessed through nutrient status, inflammation markers and lifestyle factors.
Programme Micronutrient optimisation · IV infusion therapy
Allergy
Reactions to food or environmental triggers. Testing identifies specific sensitivities rather than relying on elimination alone.
Programme Gut microbiome programme
Frequent headaches
Recurring headaches. May relate to sleep, hydration, blood glucose, hormonal patterns or muscular tension.
Programme Stress management
Typically assessed with Inflammation profiling including hs-CRP, allergy testing, micronutrient profiling, metabolic panel
Nutrient status
Nutrient deficiencies are common, frequently silent, and easy to correct once identified. Vitamin D insufficiency is widespread even in sunny climates, because most daily life happens indoors. Magnesium and iron status similarly influence energy, sleep, muscle function and mood in ways that are easy to attribute to something else.
Vitamin D deficiency symptoms
Fatigue, low mood, or bone and muscle discomfort. Common even in tropical climates, and simple to measure.
Programme Micronutrient optimisation
Magnesium deficiency symptoms
Cramps, poor sleep or muscle tension. Worth measuring rather than supplementing blind.
Programme Micronutrient optimisation
Typically assessed with Micronutrient profiling, iron studies, vitamin D assessment, dietitian consultation
A note on anxiety and depression
These are included because physical factors such as thyroid function, vitamin D status, inflammation and sleep can genuinely contribute, and are worth assessing. A longevity screening is not a substitute for mental health care. If low mood or anxiety is affecting your daily life, please speak with a doctor or mental health professional, and do that alongside rather than instead of anything here.

Common questions
Can several of these symptoms be connected?
Frequently, yes. Fatigue, weight gain, brain fog, low mood and poor sleep often share underlying contributors such as insulin resistance, thyroid function, chronic inflammation or sleep disruption. This is why assessing them together usually explains more than investigating each one separately.
I feel generally unwell but my check-up was normal. What now?
Standard check-ups are calibrated to detect established disease, so they stay quiet during the long period when biology is drifting but has not crossed a clinical threshold. A more detailed assessment measures markers such as fasting insulin, ApoB, inflammation and body composition that a routine panel does not include.
Do I need to have symptoms to book an assessment?
No. Many of the processes that shape long-term health are silent for years, which is why measurement is most valuable when you feel well. Feeling healthy and carrying meaningful underlying risk are entirely compatible.
Which of these concerns can actually be measured?
Most have measurable contributors. Body composition, insulin sensitivity, thyroid and sex hormones, inflammation markers, nutrient status, lipid particle count and cardiorespiratory fitness are all directly assessable, and together they explain a large share of the symptoms listed here.
Is this a diagnosis?
No. This page describes concerns commonly raised and what they may relate to. It is educational and does not diagnose any condition. Interpretation of your own results should always happen with a doctor.
Start with what is measurable
Most of these concerns have contributors that can be assessed directly. A Hayat longevity screening looks at them together, so the picture makes sense as a whole rather than as separate complaints.
Book a screeningThis page is educational. It describes concerns commonly raised and what they may relate to, and it does not diagnose, treat or predict any condition in any individual. Symptoms can have many causes, including some that need prompt medical attention. If a symptom is new, severe, or worsening, please see a doctor rather than waiting for a scheduled assessment.
