Thyroid Health and Fatigue: When Bangalore Professionals Should Get Tested

If you are constantly tired despite sleeping adequately, gaining weight without changing your diet, and feeling cold when everyone else is comfortable, a thyroid test is worth doing before you attribute all of it to work stress.

Here is the short answer: a single TSH blood test detects hypothyroidism. It requires no fasting, and delivers results within 24 hours. Treatment, when needed, is usually one inexpensive tablet daily.

How Common Is Hypothyroidism in India?

More common than most people realise. Research indicates the prevalence of hypothyroidism in India is approximately 10.95 percent, meaning roughly 1 in 10 adults is affected. Women develop it around three times more often than men, and rates peak between ages 35 and 60.

A significant proportion of cases go undiagnosed. The reason is straightforward: the symptoms arrive gradually and look exactly like ordinary exhaustion, which is easy to explain away when you work long hours in Bangalore's IT corridor.

The Symptom That Shows Up Most Often: Fatigue

Indian clinical data is consistent on this point. In the Indian Thyroid Registry study of adult hypothyroid patients, fatigue was the most common presenting symptom at 60.17 percent, followed by weight gain with poor appetite at 36.22 percent, poor memory and concentration at 19.81 percent, constipation at 18.15 percent, and feeling cold at 15.21 percent.

A separate Indian hospital study found fatigue present in 62 percent of hypothyroid patients at presentation.

The problem is that fatigue is also the symptom of anaemia, Vitamin D deficiency, B12 deficiency, poor sleep, depression, and chronic stress. All of these are common in Bangalore's professional population, and several often coexist.

Loss of the outer third of the eyebrows is a classic clinical clue that is easy to miss and worth checking in a mirror.

Which Thyroid Tests Should You Get?

Interpreting the pattern:
Raised TSH with low free T4 means overt hypothyroidism. Treatment is indicated.
Raised TSH with normal free T4 means subclinical hypothyroidism. Whether to treat depends on the TSH level, symptoms, pregnancy status, and antibody positivity. Your doctor will discuss this with you.
Low TSH with raised T4 or T3 suggests hyperthyroidism, which is a different condition requiring different management.

Who Should Get Tested?

The American Thyroid Association recommends routine TSH screening from age 35, repeated every 5 years. India does not currently have national screening guidelines, which means testing is largely symptom-driven.
Get tested if you have:

• Persistent fatigue not explained by sleep or workload
• Unexplained weight gain or difficulty losing weight
• Hair fall, dry skin, or eyebrow thinning
• Heavy or irregular periods
• A family history of thyroid disease
• Another autoimmune condition such as type 1 diabetes, coeliac disease, or vitiligo
• Difficulty conceiving or a history of miscarriage
• You are pregnant or planning pregnancy

Pregnancy is particularly important. Untreated hypothyroidism in pregnancy affects fetal neurodevelopment, and thyroid requirements increase significantly during pregnancy.

An Important Note on Iodine and Salt

Iodine deficiency was historically the leading cause of hypothyroidism in India, which is why the universal salt iodisation programme was introduced in 1983 and has been broadly successful.

There is a current trend toward using pink Himalayan salt in place of iodised salt. Pink salt has low and inconsistent iodine content. Using it exclusively removes a reliable dietary iodine source. If you have switched entirely to pink salt, this is worth discussing with your doctor, particularly if you have thyroid symptoms.

What Treatment Involves

Hypothyroidism is treated with levothyroxine, a synthetic form of the T4 hormone. It is taken once daily on an empty stomach, typically 30 to 60 minutes before breakfast, with water only. Calcium, iron supplements, and antacids interfere with absorption and should be taken at least 4 hours apart.

TSH is rechecked 6 to 8 weeks after starting or changing a dose, then annually once stable. Most people feel meaningfully better within 4 to 8 weeks of reaching the correct dose.
