Leaky gut is another condition linked to the following: digestive problems, headaches, sinusitis, asthma and eczema. The term ‘leaky gut’ means that a person’s intestinal lining has become filled with holes, which means that large, undigested food molecules, yeast and toxins are being allowed through into their bloodstreams. Symptoms vary but the following can be signs of leaky gut: multiple food sensitivities, nutritional deficiencies, diarrhoea or constipation, skin rashes, a poor immune system, headaches, memory loss, cravings for sugar and fatigue. Leaky gut may be caused by a diet high in sugar or flours, stress, inflammation, medications, yeast and zinc deficiency. It can be very difficult to treat and generally requires a combined program of supplements, probiotics, diet and enzymes put in place by a naturopath or dietician. As with candida overgrowth, prevention or early treatment in children is crucial in order to stop this from contributing to further immune problems.
