Constipation is a symptom that affects most people at some stage of their life (pregnancy, the elderly, etc.).
Bloating is characterised by the presence of excess gas in the digestive tract. The excess air is eliminated by passing wind (flatulence) or burping (eructation).
The gases produced are derived from the fermentation of food when it comes into contact with the bacteria of the gut microbiota.
Excess gas is promoted by stress, swallowing air while eating, drinking alcohol or smoking, fizzy drinks, etc.
Due to their immature microbiota, babies and young children can suffer from indigestion, causing intestinal gas.
