Here are some things you can do to reduce the gas:

1
Take the Metformin pill as directed by your health care provider. Generally, one pill is prescribed to be taken along with dinner. Swallow the pill whole. Do not chew or crush the pill, as this will alter the manner in which the medication is absorbed into your blood.

2
Eat small meals several times each day. Smaller-sized meals will prevent your stomach from becoming overloaded with food. When the stomach is filled to capacity, undigested food sits in the digestive system, expanding and creating gas.

3
Reduce the amount of fats and sugars in your diet. When large amounts of fat are ingested, digestion rates are slowed to prevent large amounts of fat from being released into the blood. Slower digestion rates lead to increased flatulence, as gas builds-up in empty spaces within the digestive system.

4
Avoid eating spicy foods. Spicy foods excite digestive acids, causing gas to be expelled throughout the digestive system.

5
Take a gas reducing supplement. Simethicone is the active ingredient in many over-the-counter gas relief medications. Ginger is a natural remedy that can help relieve nausea and gas buildup. Regulate digestion by adding a serving of yogurt or active probiotic supplements to your diet, to regulate the digestive process.

6
Consult your doctor, if the pressure and excessive flatulence continues. Your doctor may be able to alter your prescription to offer some relief.
