The symptoms of leaky gut syndrome are varied and do not only affect the digestive tract. Common complaints include flatulence, diarrhea, constipation, food intolerances, a weakened immune system, skin problems, chronic fatigue and hormonal imbalances. Psychological symptoms such as anxiety, depressive moods and concentration problems are also common. This complexity makes diagnosis difficult, but it is precisely this wide range of symptoms that is typical of a permeable intestinal wall. Anyone showing several of these signs should consider a targeted intestinal diagnosis.
