Fatigue

What to note before you see your GP

A few notes written beforehand make the appointment more useful. Your doctor will want to know what the tiredness feels like and whether rest helps, how long it has lasted and how quickly it came on, your sleep, any other symptoms, your diet, exercise, alcohol or other substance use, and every medicine you take. Also note any heavy periods or other bleeding, whether your mood has been low or flat, and whether anyone has heard you snore loudly or stop breathing in your sleep (see mild insomnia). If you share a bedroom, bring that person along.

Common causes your GP can check

Iron deficiency, an underactive thyroid, obstructive sleep apnoea and depression are all recognised causes. Iron and thyroid levels are checked with blood tests, and sleep apnoea with a sleep study. Supplements are not a shortcut: most people do not need them, and you should see your doctor before taking iron, because too much can cause iron poisoning. See your GP if fatigue lasts more than 2 weeks without improving, or sooner if it worries you, stops you doing things or comes with weight loss.
