Can my symptoms be diagnosed as diabetes?

Patient's question:

Recently, I've been eating and drinking a lot, and having bowel movements frequently, especially a lot. Also, my weight has been increasing rapidly. I don't want it to be like this. I want to go to the hospital for a thorough check-up. Everyone, how can I be diagnosed with diabetes? If it's not the case, then I don't need to go to the hospital. Thanks

Doctor's answer:

The typical symptoms of diabetes include polydipsia, polyphagia, polyuria, and weight gain, which are known as the "three highs and one low" symptoms. If you experience these symptoms again, it is recommended that you visit a hospital promptly to have your blood sugar levels checked. If the random blood sugar test results are below 11.1 mmol/L, it is advised to further undergo a glycosylated hemoglobin test and a glucose tolerance test. If the examination results indicate the presence of diabetes, long-term oral hypoglycemic medications or insulin therapy will be necessary.
