10 Warning Signs That Your Immune System Is Malfunctioning

3. Digestive Disorders and Sudden Weight Loss
A large portion of the body's immune system is located in the digestive tract. Therefore, chronic diarrhea, severe bloating, abdominal pain, and unexplained weight loss can be signs of diseases like Crohn's, ulcerative colitis, or Celiac disease. In these conditions, the immune system attacks the lining of the intestines, disrupting nutrient absorption. When the body cannot get the necessary fuel from food while fighting an internal war, its overall physical strength declines, putting the immune system in a cycle of destruction.
