Hormones & metabolism

Hormones are chemical messengers that set the pace for your metabolism, growth, mood, and sleep. This section covers diabetes, thyroid conditions, obesity, and disorders of the adrenal and pituitary glands. You will find what causes each one, why the symptoms are often vague and slow to arrive (tiredness, weight change, feeling cold or hot), how blood tests pin them down, and what treatment looks like day to day. Many of these are lifelong but very manageable once identified. See a doctor for unexplained weight change, constant thirst, or fatigue that rest does not fix.
