Your digestive system does more than process food; it is crucial for absorbing both macronutrients and micronutrients. When something is wrong with your gut, it often shows through subtle signs in your body. Here are five signs to watch for, with the fifth being the most common, said Dr Saurabh Sethi, gastroenterologist and interventional endoscopist, in an Instagram reel.
1. Muscle cramps
You may be low in magnesium, potassium, or calcium, especially if you sweat excessively.
Dr. Saiprasad Girish Lad, a consultant gastroenterologist, hepatologist, and therapeutic GI endoscopist at Wockhardt Hospitals, Mumbai Central, agreed that frequent cramps, especially after exercise or at night, could indicate a lack of electrolytes. 'You lose these minerals through sweat, and they may not be absorbed well if your digestive health is poor, especially with conditions like IBD, IBS, or chronic diarrhea,' said Dr Lad.
2. Grinding your teeth at night
It is often linked to stress or sleep issues. But also check your magnesium and B vitamins.
Dr Lad explained that low levels can affect nerve function and the quality of your sleep. 'If you have gut inflammation or absorption issues, these nutrients may not be adequately taken in even if you eat a good diet,' said Dr Lad.
3. Hair is falling out more than usual
It could be a sign of low iron, zinc, protein, or Omega-3s, especially in women, Dr Sethi suggested.
'Since your stomach and small intestine start absorbing iron and protein, gut issues like gastritis, acid imbalance, or celiac disease can significantly contribute to hair loss,' said Dr Lad.
4. Tingling or numbness in fingers
Often due to vitamin B12 deficiency, especially if you are vegan or over 50. Consider a vitamin B12 supplement if you are a vegan, said Dr Sethi.
According to Dr Lad, B12 needs a healthy stomach lining and intrinsic factor for absorption. 'Conditions like atrophic gastritis, long-term antacid use, or gut surgery can disrupt this process,' said Dr Lad.
5. Brain fog that won't quit
You may need more DHA, an omega-3 fatty acid, which is crucial for brain health and can be found in fatty fish or fish oil supplements.
Dr Lad said the most common signs are vague dizziness or difficulty concentrating. 'This is often related to low DHA, a vital omega-3 fat, when your diet lacks fatty fish or absorption is hindered by poor gut health. DHA supports brain function and overall mental clarity,' said Dr Lad.
While multiple factors can contribute to cognitive sluggishness, DHA deficiency is a well-recognised cause, especially in individuals with low dietary fish intake, affirmed Dr Narander Singla, lead consultant, internal medicine, CK Birla Hospital, Delhi.
Experts agreed that Dr Sethi's advice is medically sound, and anyone regularly experiencing these symptoms should consider having their nutrient levels checked through blood tests to address any underlying deficiencies effectively. 'If you notice these signs, it is not just about what you eat, but how well your gut processes it. A gastroenterologist can help determine if malabsorption or digestive problems are quietly draining your nutrient reserves,' said Dr Lad.
