I have a desk job, so most of the time I spend sitting in front of the computer. Last year I had some viral fever and doctor had given me high dosage medicines. Now I have put on more weight & I have serious gastric problem. Every day my stomach gets bloated up. Recently I have started walking in the morning about 4.5 - 5 kms approx. Where as my tummy is still big & other parts of my body like leg, shoulders are getting slim. But my tummy is in tact. No changes. Please suggest how to control my gastric issue and reduce tummy.
