Hello Ana and hope you are doing well.
IBS is a diagnosis of exclusion. If all the tests to rule out other disorders are done and found to be negative, then the diagnosis of IBS is made. Besides IBS, your symptoms could be due to malabsorption, inflammatory bowel diseases and various infections of the colon. So, for now you follow some good lifestyle measures for the bloating to decrease. Eat food rich in plenty of fresh fruits and vegetables, avoid spicy and fatty food, avoid smoking and eliminate alcohol. Do not consume caffeinated beverages. Practice good relaxation techniques like yoga and meditation. Exercise regularly. Go for long relaxed walks. Maintain a food diary and try to identify those foods which are likely to produce bloating and avoid them. If these measures don't help or if your symptoms worsen, consult your primary care physician.
Hope this helped and do keep us posted.
