Although embarrassing, everyone passes wind. Bloating and gas can be uncomfortable. There are a number of things that can help but if you are suffering more than normal seek advice from a medical professional.
How you Eat
Chew your food throughly and take your time, try not to rush meals as this can cause the swallowing of excess air. Chewing also releases digestive enzymes to help digest your food better.
Try not to lie down after eating.
High fat meals can cause wind as it is not digested very well, its best to avoid these types of foods if possible.
What you eat is important, try to avoid foods high in fat and sugar, try to eat fresh vegetables and fruit. Exercise is also helpful in removing wind.
Again thoroughly chewing your food will help to reduce odours, however there are activated charcoal tablets that can help.
