When you swallow some air, the air goes into your body. When it is time for the air to come out, it emerges from the same way that it went in. This is basically your body ejecting the air that you had swallowed. You will be pleased to know that burping is not a medical condition at all, even though many people suffer from continuous burps. Burping is the body's way of removing the air that we have swallowed. This helps the body get rid of all the gas that has accumulated in the body. Even though in some parts of the world burping after a meal is indicative of the eater's appreciation of the food, in most parts of the world this is not the case and burping is frowned upon in society. For this reason your anxiety about your burping is understandable.
If you are burping after you have drunk liquids this could mean that you are swallowing air when you are drinking the liquid. That is why, soon after you have finished drinking something you burp. This is nature's way of ensuring that the air that you have swallowed is sent back.
The basic solution to this is that you don't swallow quite so much air. Sometimes when people get used to burping, they indulge in loud burps and continue burping for some time. Instead of encouraging yourself to burp, you can try stifling the burp. When you make an attempt to control the burp you will find that you are burping far less than usual.
If you are regular smoker, then you should immediately stop this. When you smoke, you invariably swallow a lot of air along with the smoke. It is this air that demands an outlet and causes you to burp. You should also learn to eat slowly. Chewing well helps in reducing the rate of your eating. Since you suffer from burps after you have swallowed fluids, you should try to drink fluids slowly. Try not to open your mouth too wide when you are eating food and particularly when drinking fluids, and try to be aware of whether you are swallowing air when doing so. You have not mentioned which fluid causes you to burp loudly. If you drink carbonated drinks regularly, then this is the reason why you burp so frequently. You should stay away from aerated drinks. You should also avoid drinking any liquid through a straw since drinking the fluid with a straw increases the amount of air that you swallow and makes you burp more often.
