Hi Doctor, I am having problem of mouth breathing in night and due to that I woke up early every morning as my mouth taste in bad condition. This problem I am facing everyday now. My throat is also feeling sore and voice is a bit heavier. Is that due to this? Another problem I am facing is with Stomach, sometime I feel pain and having problem of gas inside the stomach. I Belch a lot many times due to this problem. I am not sure if these problems are inter related or not but due to this I feel sleepy and also looking a bit thin now a days. I do exercise 4-5 days in a week. Can you please suggest me which doctor I need to consult. Thanks, Sandeep.
