Hello and hope you are doing well.
The frequent need to burp and expel gas suggest abdominal bloating with gas. Bloating can cause a lot of discomfort. If you have been investigated to rule out disorders of the colon, the bloating can happen with consumption of excess sugars, indigestion and aerophagia. Try to limit voluntarily swallowing excessive air. Check to see if any specific food is aggravating the bloating and try to avoid the same. In general try to avoid cabbage, broccoli, cauliflower and asparagus. Certain medications and food additives too can cause bloating. Check on these. Also, try to include yogurt in your diet as it is a probiotic which replaces lactobacillus acidophilus (good bacteria) that helps with digestion.
Avoiding triggering factors which initiate or worsen the symptoms like stress – oversensitive bowel may react to normal stress of everyday living. Worrying about the symptoms can create a vicious cycle, making the symptoms worse. Try to combat stress with relaxation techniques or regular exercise.To expel intestinal gas, try taking a brisk walk or getting some other form of exercise. Frequent exercise can help keep the intestines working more efficiently and aid with digestion. Also, OTC medications such as simethicone may help with flatulence.
Hope this helped and do keep us posted.
