Carbonated drinks can upset your stomach. Actually, soda, sparkling water and energy fizz drinks are filled with carbon dioxide gas. This gas gets trapped in the stomach and increases the problem of bloating, belching and flatulence in many people. Zero sugar or healthy soda can also cause the same problem because the problem is of gas and not just the ingredients.

Protein shakes can also increase stomach problems. Lactose present in protein shakes, especially dairy-based products, does not suit many people. This can cause gas, stomach pain and bloating. At the same time, plant-based shakes can also cause digestive upset due to sweeteners and gums. Drinking too much protein at one go also puts pressure on the stomach.

At the same time, both natural carbonation and fermentation are present in beer which increases gas in the stomach. The yeast and carbs present in beer ferment in the intestines and form gas. In such a situation, beer, wine or kombucha can increase bloating and heaviness in some people.

Apart from this, coffee increases acid in the stomach. Caffeine can cause problems like gas, acidity or diarrhea in sensitive people. It stimulates the intestines. Due to which some people get relief but in many people problems like gas and prickling increases.

At the same time, lactose present in milk is not digested by many people. Even a little milk in tea or coffee can cause gas, stomach pain and bloating. This is the reason why many people feel heavy in the stomach after consuming dairy.

Packaged juices, soft drinks and sports drinks contain more sugar which gets digested quickly and ferments in the intestines. This produces gas, especially high protein drinks which further upset the stomach.

Orange, seasonal or lemon juice are also more acidic. Drinking these on an empty stomach irritates the lining of the stomach and increases problems like gas and bloating.
