### output:

welcome to Chat Doctor and I can understand your concern. Swimming is one of the good exercise to keep your body fit, as well as to reduce weight. Yes cola contains lots of sugar. If you are diabetic i.e. high blood sugars, fasting blood sugar >100 and post postprandial sugar level>140 considered as diabetic. If you are diagnosed as diabetic as u have control your sugar level first, by diet like using more of wheat, ragi, vegetables and avoid rice, sugar added food, by doing regular exercise like walking or swimming, and you have to start antidiabetic Chat Doctor. If your sugar levels gone too high, then you may suffer from usual breathing, in that bad smell comes out from your mouth. But it is rare. Common other causes of bad smell breathing are oral candidiasis or any bacterial infection. Tips1. Maintain oral hygiene2. Use mouthwash after each meal3. Do gargle with hot water and salt and about your pin and needle sensation, you might be having peripheral neuropathy because of diabetes.I hope I have answered your query thank you take care
