In her late teens, my daughter was diagnosed with delayed digestion. The Pill made a big difference, but she burps a lot. Any advice? Burping can be caused by swallowing excess air through drinking fizzy drinks, drinking through a straw, smoking, sucking boiled sweets, chewing gum or sniffing a lot, so simple avoidance may solve the problem. But it can also be due to delayed digestion. When there are insufficient digestive enzymes, food stays for too long in the stomach, producing gases, and leading to bloating and belching. An improved diet may encourage the production of digestive enzymes; they can also be taken in pill form (try Digestizyme, by Nature's Best, 01892 552117). Ginger, too, stimulates these enzymes - try a cup of ginger tea made from fresh ginger root with each meal. Cardamom, fennel seed or clove tea, made by boiling the herb for 10 minutes, would also work.
