FAQ
Frequently Asked Questions
Hypothyroidism causes a low basal metabolic rate, but 'low metabolism' is a broader, less precise term. Hypothyroidism is a specific medical diagnosis.
Most forms, like Hashimoto's, are chronic and managed with lifelong hormone replacement therapy, which effectively reverses symptoms but is not a cure for the underlying gland failure.
Hypothyroidism is an underactive thyroid (too little hormone), causing slow metabolism. Hyperthyroidism is an overactive thyroid (too much hormone), causing a fast metabolism, anxiety, and weight loss.
If left untreated, it can lead to serious complications like heart problems, infertility, and myxoedema coma. However, with proper diagnosis and daily medication, it is typically very well-managed.
