Why Am I Always Tired? 7 Medical Reasons Women in Pakistan Miss
Why Am I Always Tired? 7 Medical Reasons Women in Pakistan Miss
Fatigue in women is dismissed far too often. These are the medical causes worth investigating.
I've sat across from too many women who've been told their exhaustion is "just stress" or "you're a mother, of course you're tired." Sometimes those explanations are right. But often, there's a measurable biological cause being missed, either because it wasn't tested for or because the symptoms were normalised before they got a chance to be investigated.
Pakistan has specific epidemiological patterns that make certain deficiencies and conditions particularly common in women. Here's what's worth knowing.
7 Medical Causes of Fatigue in Women
Iron deficiency is the most common nutritional deficiency globally, and in South Asian women, the rates are high: roughly 50 to 60% of reproductive-age women in Pakistan are affected. Causes include heavy menstrual bleeding, inadequate dietary iron (particularly in women avoiding red meat), and multiple closely spaced pregnancies that deplete stores.
Fatigue from iron deficiency is a specific kind: a dragging, heavy tiredness even after adequate sleep. You feel breathless with mild exertion. You might have headaches, difficulty concentrating, and cold hands and feet. Some women describe a craving for ice (pica, specifically pagophagia), which is surprisingly common and specifically associated with iron deficiency.
The thyroid gland regulates the metabolic rate of every cell in your body. When it underproduces thyroxine (T4), everything slows: your digestion, your heart rate, your cognition, your energy production. The result is fatigue that feels different from simple tiredness, more like running through water.
Classic symptoms: fatigue, weight gain despite normal eating, constipation, cold intolerance, dry skin and hair, hair loss (particularly from the outer third of the eyebrows), depression, and heavy periods. The condition is significantly more common in women than men, with a 7:1 female-to-male ratio. Autoimmune thyroiditis (Hashimoto's disease) accounts for most cases in non-iodine-deficient populations.
In Pakistan, iodine deficiency contributes to hypothyroidism in some regions, particularly in mountainous areas away from coastal fish and iodised salt access.
Vitamin D deficiency is paradoxically common in sunny countries, and Pakistan is no exception. Studies suggest 70 to 80% of Pakistani women are deficient. The reasons: cultural and religious dress practices reducing skin sun exposure, avoiding outdoor activity in high heat, and dietary patterns low in fortified foods.
Vitamin D deficiency causes musculoskeletal pain, bone aches, generalised fatigue, and low mood. It's also been associated with immune dysfunction and worsening of several autoimmune conditions. Severe deficiency causes osteomalacia (bone softening), which presents as bone pain and muscle weakness that's sometimes misdiagnosed as fibromyalgia.
PCOS affects around 8 to 13% of women globally, and likely higher in South Asian populations. At its metabolic core, PCOS involves insulin resistance, which means your cells require more insulin than normal to take up glucose. This creates a chronic energy availability problem: tissues aren't using fuel efficiently.
The fatigue in PCOS is compounded by several factors: insulin resistance itself causes exhaustion; many women with PCOS have sleep apnoea (a known but underappreciated comorbidity); PCOS increases the risk of depression; and the irregular periods cause significant blood loss in some women, contributing to iron deficiency.
South Asian women develop insulin resistance and type 2 diabetes at lower BMIs than their European counterparts. Many are not routinely screened until their 40s, by which point significant metabolic damage has accumulated. The pattern of body fat distribution in South Asian women (greater visceral adiposity at lower total body weight) is itself a risk factor independent of BMI.
Fatigue from diabetes: your cells can't effectively use the glucose in your blood, so despite high blood sugar, you're energy-starved. Add the disrupted sleep from frequent urination, and you're exhausted on multiple fronts.
Depression is significantly underdiagnosed in Pakistani women. Stigma around mental health, the cultural expectation of resilience, and the tendency for Pakistani women to express psychological distress through physical symptoms (somatisation) all contribute to missed diagnoses.
Fatigue is one of the core diagnostic features of depression. It's a specific biological fatigue caused by disrupted neurotransmitter function and altered sleep architecture, not simply "feeling sad." Women with depression are more likely to present to a GP with fatigue, pain, and sleep complaints than with mood symptoms described as such.
Coeliac disease causes fatigue through malabsorption: the immune-mediated gut damage means you absorb fewer calories, less iron, less folate, less B12, and less vitamin D from your food. You eat adequately but remain nutritionally depleted. The classical GI presentation (diarrhoea, bloating, weight loss) is absent in many patients, particularly women, who often present with fatigue, anaemia, and bone pain instead.
Coeliac disease is underdiagnosed in Pakistan partly because the atypical presentation is less recognised, and partly because gluten-free eating is more socially difficult in Pakistani food culture (where wheat is a staple). But diagnosis is important: uncontrolled coeliac disease carries significant long-term risks including lymphoma and osteoporosis.
Fatigue is one of the most common reasons women see a doctor, and one of the most commonly dismissed. A thorough investigation takes less than a day of blood tests. Dismissal takes 5 seconds.
What to Ask Your Doctor
A Note on "Normal" Ranges
Lab reference ranges are population averages, and they can be misleading. A ferritin of 12 micrograms/L is technically "within normal" in many labs (range 5 to 204), but it's functionally deficient in a woman with symptoms. A TSH of 4.5 is technically within range (0.4 to 5.0), but some endocrinologists treat it in a symptomatic patient with positive thyroid antibodies.
Symptoms matter alongside numbers. A result "in range" doesn't mean the number is optimal for you.
The Summary
Persistent fatigue in women has specific, treatable, medical causes that are frequently missed. In Pakistan, iron deficiency, vitamin D deficiency, and hypothyroidism are particularly prevalent. PCOS, undiagnosed diabetes, depression, and coeliac disease round out most of the common picture.
If you've been exhausted for months and been told it's "just stress," push for blood tests. A comprehensive fatigue panel takes 20 minutes and tells you a lot. Exhaustion is not a personality trait; it's often a symptom.
