Your digestive system does more than break down food, it plays a crucial role in absorbing essential nutrients your body needs to function. When nutrient absorption is compromised, your body may send subtle signals that something is off.

Experts highlight five common signs that could indicate nutrient deficiencies, urging individuals to monitor their health closely and seek medical advice if these symptoms persist. Here's what to watch out for:

1. Muscle Cramps

Frequent cramps, especially after exercise or during the night, can signal low levels of magnesium, potassium, or calcium. These minerals are lost through sweat and may not be adequately absorbed if digestive health is compromised. Chronic gut issues like IBD, IBS, or ongoing diarrhoea can increase this risk.

2. Teeth Grinding at Night

Though often linked to stress or sleep disturbances, nighttime teeth grinding may also point to low magnesium and B vitamin levels. Poor nutrient absorption due to gut inflammation can impact nerve function and disrupt restful sleep.

3. Excessive Hair Loss

More hair than usual falling out, particularly in women, could be linked to deficiencies in iron, zinc, protein, or Omega-3 fatty acids. Since absorption of these nutrients starts in the stomach and small intestine, digestive issues such as gastritis or celiac disease can worsen hair loss.

4. Tingling or Numbness in Fingers

This is often a sign of vitamin B12 deficiency, which is more common in vegans or those over 50. Proper absorption of B12 depends on a healthy stomach lining and the presence of intrinsic factor. Conditions like long-term use of antacids, gut surgeries, or atrophic gastritis can hinder this process.

5. Persistent Brain Fog

This commonly overlooked symptom may stem from low levels of DHA, an essential omega-3 fatty acid vital for brain function. Found in fatty fish and fish oil supplements, DHA supports mental clarity and cognitive health. Poor gut absorption or a diet lacking in these nutrients can lead to lingering fogginess or difficulty concentrating.

What to Do

Health professionals stress that these signs shouldn't be ignored. Regular blood tests can help detect underlying nutrient deficiencies early. It’s not just about what you eat, but how well your digestive system absorbs those nutrients. If symptoms persist, consulting a gastroenterologist or nutrition specialist can help uncover any malabsorption issues or underlying digestive problems.
