An underactive or overactive thyroid can cause tiredness, weight change, hair fall and mood changes. We confirm it with the right tests, get the dose right and keep it right.

Tiredness, weight gain, constipation, dry skin, feeling cold, heavy periods. Treated with daily thyroxine and regular TSH checks.
Weight loss, fast heartbeat, tremor, sweating, anxiety. Needs the cause found first, often Graves' disease or a thyroid nodule.
Slightly abnormal TSH with normal T4. Not everyone needs tablets: we decide on symptoms, antibodies, age and pregnancy plans.
TSH targets are tighter before and during pregnancy. Doses often need to rise early in pregnancy.
Weight that won't shift, hair fall and irregular periods. Thyroid, insulin resistance and PCOD are checked together.
A lump or swelling in the neck is examined and, when needed, sent for ultrasound.
Most thyroid problems are easy to control once the dose and the way you take the tablet are right.
TSH and free T4, with anti-TPO antibodies when the cause is unclear. We also check vitamin D, B12, iron and haemoglobin, because their symptoms overlap.
The dose depends on weight, age, heart health and pregnancy. Older adults and heart patients start low and go slow.
Thyroxine on an empty stomach, 30–60 minutes before breakfast or tea. Keep calcium, iron and antacids 4 hours apart.
TSH again 6–8 weeks after any dose change, then every 6–12 months once stable. Reports can be reviewed online.
For most adults, the lab range is about 0.4–4.0 mIU/L, though it varies by lab, age and pregnancy. One borderline result is usually repeated before starting treatment.
An underactive thyroid can add a few kilos, mostly fluid, and make weight loss harder. Once TSH is normal, extra weight is usually due to diet, sleep, activity or insulin resistance, which we also treat.
Most people with hypothyroidism from Hashimoto's thyroiditis need lifelong treatment. Thyroid problems after pregnancy or during an illness can be temporary and are re-tested.
Low vitamin D or B12, anaemia, poor sleep, sleep apnoea, depression or blood sugar problems are common reasons. They are worth checking before changing the thyroid dose.
No. Coffee, tea, milk and food reduce its absorption. Take it with water only, then wait 30–60 minutes.
Yes. Once you have been examined, dose changes based on reports work well as online follow-ups.
