Fenugreek seeds, widely used for their health and culinary benefits, can also cause a range of side effects, particularly when consumed in large amounts or as concentrated supplements. Potential issues include digestive discomfort, nausea, hypoglycaemia, allergic reactions, and changes in body odour. Pregnant women and individuals on certain medications should exercise caution, as fenugreek can interact with drugs and may pose risks during pregnancy. Rarely, excessive intake may lead to electrolyte imbalances or respiratory irritation, especially when handling powdered forms. Experts recommend starting with small amounts, monitoring for adverse reactions, and consulting a healthcare professional before use, especially for those with pre-existing conditions or on medication.
