More than a stomach ache
Over 200 possible symptoms.
When people picture celiac disease they think of diarrhoea and cramps. Those are real — chronic or recurrent diarrhoea, bloating, abdominal pain, and weight loss are the classic digestive signs.1 But celiac has been linked to more than two hundred symptoms, and many have nothing to do with digestion.2 This is exactly why it hides for so long.
The silent signs
The symptoms nobody connects to the gut.
Because the damaged intestine stops absorbing nutrients, celiac often announces itself somewhere else entirely:
- Iron-deficiency anaemia that doesn't improve with supplements — the single most common sign outside the gut.3
- Constant fatigue and weakness, often blamed on everything but celiac.3
- Low bone density (osteopenia/osteoporosis) from poor calcium and vitamin D absorption.3
- Unexplained infertility or recurrent miscarriage.3
- An itchy, blistering skin rash (dermatitis herpetiformis) — a celiac sign on the skin.1
- Deficiency in B12 or folate, sometimes with tingling, numbness, or low mood.3
Some people have no obvious symptoms at all — "silent" celiac — and are only found through screening because a close relative has it.
Children vs adults
In kids, it can stall growth.
In children the picture often shows up as failure to gain weight, short stature, delayed puberty, irritability, or a swollen belly with thin limbs.2 In adults the digestive symptoms are frequently mild or absent, and the extra-intestinal signs — the anaemia, the fatigue, the bone loss — dominate.1
Why India misses it
Diagnosis here takes years — it shouldn't.
Despite affecting around 1 in 100 people in the north, celiac is heavily under-diagnosed in India.4 The reasons are simple: low clinical suspicion, symptoms that overlap with common conditions like IBS, and the many "atypical" presentations that don't look like a gut problem at all.4 The result is people spending years — sometimes decades — undiagnosed.
Take this to your doctor. If you have unexplained anaemia, long-running gut symptoms, or a first-degree relative with celiac, ask specifically about testing. And keep eating gluten until you're tested — see getting diagnosed for why that matters.
