The term flatulence indicates the accumulation of an intestinal gas produced by the fermentation of undigested food in the colon. It may be associated with constipation, changes in the intestinal flora, triggered by taking antibiotics or other drugs, problems in the absorption of carbohydrates, ingestion of air or digestive disorders.

What kind of diseases can be associated with flatulence?
The diseases that may be associated with flatulence are the following:
    •    Food allergy
    •    Abdominal angina
    •    Celiac disease
    •    Cholecystitis
    •    Colitis
    •    Food intolerance
    •    Lactose intolerance
    •    Irritable bowel syndrome

Remember that this is not an exhaustive list and it is highly recommended to consult your doctor, in case of symptom’s persistence. 
What is the therapy for flatulence?
Flatulence often resolves on its own, but in some cases it may be useful to take probiotics or supplements that promote the digestion of lactose. To avoid it, one has to try and limit the consumption of foods and beverages that are considered a trigger (such as legumes, cauliflower, Integral bread, mushrooms, beer and soft carbonated drinks). In the event that the problem is associated with dairy products it may be favourable to consume products with low lactose content, or even avoid of this type of sugar. Reducing fatty foods can be also useful because slower digestion can stimulate intestinal food fermentation. Eating slowly and ensuring regular exercising are considered as preventive measures.
When is most likely to contact your doctor in case of flatulence?
It is good to seek medical attention if the symptoms are persistent or severe, manifested as diarrhea, abdominal pain, blood in the stool or change its colour, changes in stool’s frequency, unexplained weight loss or chest pain. In these cases the flatulence can be a symptom of a disorder that requires specific treatment.
