Hyperthyroidism, or an overactive thyroid, can be tricky to detect. Its symptoms often mimic other health issues like stress, anxiety, or even menopause. In mild cases, you may not feel anything unusual at all. But when left untreated, this condition can disrupt your sleep, mood, weight, and heart health. If you’ve been feeling off lately, paying attention to these signs might be time.

At Dr Batra’s®, we look beyond the symptoms to treat the root cause of thyroid imbalance. Our expert doctors use a safe, holistic approach to help you feel like yourself again.

Common Symptoms of Hyperthyroidism

Sudden weight loss despite eating well: Your body burns calories too quickly, even with normal or increased appetite.
Rapid heartbeat or palpitations: Heart rate rises above 100 bpm without exertion.
Increased anxiety or irritability: Feeling restless or overly emotional is common.
Trouble sleeping or insomnia: Difficulty falling or staying asleep due to overactive metabolism.
Muscle weakness in thighs or upper arms: Everyday tasks like climbing stairs may feel harder.
Fine, brittle hair or unexpected hair loss: Hair becomes thin, dry, or clumps.
Shaky hands or tremors: A constant hand tremble can develop without physical strain.
Excessive sweating or intolerance to heat: Feeling overly hot or sweating in cool environments.
Changes in menstrual cycle: Periods may become lighter, irregular, or less frequent.
Loose or frequent bowel movements: The Digestive system speeds up, causing more frequent bathroom trips.
Bulging eyes or double vision (Graves' disease): Inflammation behind the eyes can lead to vision problems.
Thinning skin and rapid nail growth: Skin becomes fragile, and nails grow unusually fast.

Insight from a global study by Research Gate

A study on ResearchGate found 37.83% of thyroid patients in Kerala chose homeopathy over modern and Ayurvedic medicine. Homeopathy helps regulate gland function, stimulating when underactive and calming when overactive.

FAQs

Yes, hyperthyroidism can affect your menstrual cycle. Hormonal imbalance often causes lighter, shorter, or irregular periods. Some women may even experience missed periods. If your cycle changes persist, checking your thyroid levels and seeking appropriate care is essential.

Yes, hair loss is a common symptom of hyperthyroidism. It usually results in brittle, thinning hair or unexpected shedding. The imbalance in thyroid hormone affects hair growth cycles, but proper treatment can help manage and reverse this symptom.

Although weight loss is typical, some people with hyperthyroidism may gain weight due to muscle loss, poor diet, or fluid retention. Metabolic imbalances and reduced physical strength can affect body composition. Personal dietary care and balanced treatment can help manage weight effectively.

Most patients see improvement within 6–8 weeks of starting homeopathy. A 2023 study found that 72% reported symptom relief in two months. Results depend on the condition’s severity, duration, and treatment adherence. Homeopathy offers long-term healing by addressing the root cause, not just symptoms.

Yes, elevated thyroid hormone levels can overstimulate the nervous system, leading to mood swings, irritability, restlessness, or anxiety. These emotional changes are common and often misattributed. Treating the hormonal imbalance helps restore emotional balance and mental clarity.

Yes, especially in conditions like Graves’ disease, where inflammation behind the eyes can cause bulging, dryness, eye pain, or double vision. These symptoms require prompt medical attention to prevent long-term complications and to manage the underlying thyroid dysfunction effectively.

Yes, fatigue can develop over time with hyperthyroidism. While early stages may bring high energy, prolonged hormone overproduction can exhaust the body, leading to muscle weakness, tiredness, and poor stamina. Addressing thyroid levels can gradually restore energy and strength.

Yes, hyperthyroidism affects men, too, though it’s more common in women. Men may experience symptoms like weight loss, mood changes, tremors, or reduced libido. Timely diagnosis and personalised treatment are essential for managing symptoms and maintaining overall health.
