A typical sign of food intolerance includes gastrointestinal symptoms such as bloating, gas, diarrhea, or abdominal cramps after consuming certain foods. Unlike food allergies, which can cause severe reactions, food intolerances often involve a delayed response and may vary in severity. Some individuals may experience headaches, fatigue, or skin irritations as well. Identifying and eliminating trigger foods through an elimination diet can help alleviate symptoms. Consulting with a healthcare professional is essential for appropriate testing and diagnosis to manage food intolerances effectively and maintain overall nutritional balance.
