Doctor warns that Thyroid Disease is changing in India, and many patients still don’t recognise the symptoms

For years, thyroid disease in India carried a familiar stereotype. It was seen as a “middle-aged women’s condition” linked to weight gain and tiredness. But endocrinologists across the country are now witnessing something very different. Young professionals in their 20s, teenage girls, men struggling with unexplained fatigue, and even elderly people being treated for memory decline are all turning out to have one thing in common: thyroid dysfunction.The shift is not small anymore. It is visible in clinics, workplaces, homes, and even fitness spaces. Fatigue that never leaves, anxiety without a clear reason, thinning hair, sudden mood changes, irregular sleep, and stubborn weight fluctuations are becoming part of everyday life for millions of Indians. Often, people blame stress, aging, burnout, or lifestyle. The thyroid quietly goes unnoticed.Dr Mahesh Chavan, Consultant, Endocrinologist & Diabetologist at Apollo Hospitals, explains, “Fatigue, unexplained weight gain, anxiety, hair fall and poor sleep: millions of Indians experience these symptoms every day, not realising that these point toward thyroid dysfunction.”India already carries a significant thyroid burden. According to the Indian Council of Medical Research and several hospital-based studies, nearly 42 million Indians are estimated to suffer from thyroid disorders. The thyroid gland may be small, but its impact stretches across the entire body. Sitting at the front of the neck like a butterfly, it controls metabolism, energy production, body temperature, mood regulation, menstrual health, heart rhythm, and even digestion. When hormone levels shift, life often shifts with them.One of the most overlooked groups today is young women between 18 and 35. Many appear perfectly functional from the outside. They work long hours, meet deadlines, maintain social lives, and continue to push through exhaustion. Inside, however, their bodies may already be struggling with thyroid imbalance.Dr Chavan notes that thyroid disease in younger women rarely follows textbook symptoms anymore. “They often walk into a clinic complaining of symptoms that don’t immediately appear thyroid-related, such as persistent brain fog, severe hair thinning, chronic anxiety, and unpredictable menstrual cycles.”What makes the problem harder is the culture of normalization. Constant tiredness has become fashionable in urban India. Sleepless nights are treated as ambition. Stress is worn almost like a badge of productivity. In the middle of this, thyroid symptoms disappear into the noise of modern living.Doctors are also seeing overlap with insulin resistance and hormonal conditions such as PCOS. Weight becomes harder to manage, periods become irregular, and emotional health starts fluctuating. Many women spend years treating symptoms separately without ever testing thyroid function comprehensively.The danger lies in delay. Untreated thyroid dysfunction can affect fertility, metabolism, cardiovascular health, and mental wellbeing over time.There is also a social layer attached to this. Young women are often told they are “overthinking,” “too emotional,” or simply exhausted from work culture. In many cases, the body is actually asking for medical attention.For women in their late 40s and 50s, thyroid disease can become almost invisible because its symptoms mirror menopause so closely.Mood swings, poor sleep, anxiety, sudden weight gain, fatigue, and changes in concentration are common in both conditions. As a result, many women accept discomfort as a natural part of aging without realising a treatable hormonal imbalance may be contributing to it.“Women in this age group frequently juggle work, caregiving, and family responsibilities, which can delay timely attention to thyroid-related symptoms,” says Dr Chavan.This stage of life is emotionally demanding already. Many women are managing careers while simultaneously caring for aging parents, children, and households. Health often moves to the bottom of the priority list.The result is delayed diagnosis. Instead of seeking evaluation, women continue functioning through exhaustion because society expects them to.The problem is deeper than physical health alone. Long-term untreated hypothyroidism can quietly affect cholesterol levels, heart health, bone strength, and mental health. When fatigue becomes constant, quality of life changes slowly and silently.Globally, public figures have also spoken openly about thyroid struggles, helping reduce stigma. Actress and singer Selena Gomez has discussed her autoimmune health journey publicly, while television personality Oprah Winfrey once spoke about living with thyroid-related imbalance and exhaustion. Their stories helped many people recognise that hormonal illnesses do not always “look sick” from the outside. Perhaps the biggest shift in recent years is the growing number of men being diagnosed with thyroid disorders.For decades, thyroid disease was labelled almost exclusively as a women’s health issue. That assumption delayed diagnosis in countless men who ignored symptoms for years.Today, endocrinologists are seeing more male patients with obesity-linked hypothyroidism, metabolic dysfunction, diabetes, stress-related hormonal changes, and chronic fatigue.Dr Chavan explains, “Men typically present with chronic fatigue, unexpected abdominal weight gain, low libido, and poor muscle recovery after workouts.”In many Indian households, men are conditioned to dismiss weakness until it begins affecting work performance or daily functioning. Sluggishness becomes “getting older.” Mood changes become “stress.” Poor concentration becomes “work pressure.”But thyroid dysfunction affects men differently too. Reduced energy, poor recovery from exercise, declining motivation, and cardiovascular risk factors are now increasingly linked to hormonal imbalance.There is also growing concern around sedentary lifestyles, disrupted sleep cycles, late-night eating patterns, and chronic stress among urban men. These patterns are contributing to wider metabolic disturbances, which often coexist with thyroid disease.The stereotype that thyroid disorders belong to only one gender is slowly breaking, and that may be one of the most important developments in endocrine health awareness today.Among senior citizens, thyroid disease can become extremely difficult to recognise because symptoms overlap with natural aging.Forgetfulness, slower movement, constipation, muscle weakness, balance issues, and low mood are frequently dismissed as routine signs of growing older. Families may not immediately suspect an endocrine problem.Dr Chavan describes thyroid disease in the elderly as “a master of disguise.”This is particularly important in India, where family members often assume declining energy is unavoidable with age. Many older adults quietly adapt to symptoms instead of seeking evaluation.But diagnosis in older adults requires precision. Thyroid medication doses that are too high may increase the risk of osteoporosis or irregular heart rhythms such as atrial fibrillation. Doctors therefore aim for carefully balanced, age-sensitive treatment rather than aggressive correction.The larger lesson is simple: aging and illness are not always the same thing.An older person losing interest in food, feeling unusually cold, becoming forgetful, or struggling with persistent constipation may not simply be “slowing down.” Sometimes, the thyroid is involved.Modern thyroid treatment is slowly moving beyond prescription pads and laboratory reports.Doctors now recognise that thyroid disease affects emotional wellbeing, sleep quality, productivity, relationships, and confidence. Someone with untreated thyroid imbalance may feel mentally exhausted long before blood reports appear dramatically abnormal.“Effective management means recognizing and addressing the emotional toll of this disease, correcting disrupted sleep cycles, adopting a healthier diet and targeting stress management,” says Dr Chavan.Lifestyle alone cannot reverse thyroid disease completely. But it can strongly influence symptom control and long-term outcomes.Regular physical activity, proper sleep, balanced meals, adequate protein intake, medication adherence, and stress reduction can help patients feel significantly better. Small routines matter. Consistent sleep timing matters. Even reducing screen exposure before bedtime may help improve hormonal stability indirectly.India’s growing thyroid burden is also closely tied to the realities of modern living. Longer working hours, processed food consumption, rising obesity, stress, reduced physical activity, and poor sleep hygiene are all influencing endocrine health.The conversation around thyroid disease is therefore becoming larger than medicine alone. It is now about how people live, work, rest, and respond to their bodies.And perhaps that is the real shift India is witnessing today. Thyroid disease no longer belongs to one age group, one gender, or one lifestyle. It has become a mirror reflecting the pressures modern life places on the body.Medical experts consultedThis article includes expert inputs shared with TOI Health by:Dr Mahesh Chavan - Consultant, Endocrinologist & Diabetologist, Apollo Hospitals Navi Mumbai.Inputs were used to explain how thyroid disease in India is no longer limited to one age group or gender, why symptoms are increasingly being overlooked across different stages of life, and why early diagnosis and timely medical attention are becoming more important than ever.
