How common is fatigue in coeliac disease?

Coeliac disease can damage the small intestine, reducing absorption of nutrients needed for energy and healthy blood cells. Anaemia, low iron, folate or vitamin levels, poor sleep, and the effort of coping with digestive symptoms may all add to tiredness. Fatigue can remain for a while after diagnosis, so its persistence deserves review rather than guesswork.

Describe the pattern of fatigue and mention diarrhoea, bloating, weight change, headaches, mouth ulcers, or concentration problems. If coeliac disease has not been diagnosed, speak with a clinician before removing gluten, because testing can be affected by dietary changes. If it is diagnosed, follow the prescribed gluten-free plan and attend follow-up checks. Avoid taking iron or vitamins without advice; the right supplement depends on your results.

Book an appointment when tiredness persists, affects daily life, or returns despite following your treatment plan. Seek urgent help for fainting, severe weakness, black or bloody stools, repeated vomiting, or signs of dehydration such as confusion and very little urine.

Could anaemia or another nutrient deficiency explain my fatigue? Do I need follow-up blood tests? Is my gluten-free diet nutritionally balanced, and should I see a dietitian?
