Hi…. Welcome to HEALTHCARE MAGIC... I have gone through your query and can understand your concerns... The burning sensation or cold/heat in the upper part of the stomach is a very common occurrence and a sign of digestive problems like gastritis, GERD, food allergies intolerance, or emotional stress. I will advise you to do necessary lifestyle changes like: 1.Avoiding foods that irritate the stomach such as spicy foods, tomato-based foods, citrus foods, chocolate, coffee, mint, garlic and onions may help reduce heartburn symptoms. 2.Learning to manage stress with techniques like yoga, deep breathing, prayer and meditation can help the person relax his or her body and decrease the build-up of stomach acid. 3.You can use Antacids to control the amount of acid. If antacids are not effective then the physician will prescribe H2 blockers, like Tagament, Zantac, and Pepcid. These medications work to reduce the production of stomach acid. If gastritis is believed to be a result of H. pylori bacteria, the physician will prescribe antibiotics to treat the bacterial infection. 4.Regular exercise, eliminating cigarette smoking and reducing alcohol intake also help to improve digestive health. If lifestyle changes fail to reduce or eliminate symptoms, you should consult with a physician. Hope this information helps... Thanks & Regards, Dr.Shiwani
