First of all, diet control is one of the basic treatments of diabetes treatment, otherwise blood sugar is not well controlled. It is not right for you to have hypoglycemia symptoms which are confirmed (check blood sugar) to be hypoglycemia, and for mild hypoglycemia, you can eat some fruits or drink some milk, and you should not eat too much, which will lead to high blood sugar; moreover, you should not play insulin before the next meal without eating, which will cause hypoglycemia. If the insulin injection does not cause local symptoms at the injection site such as redness, swelling, heat and pain, subcutaneous hard nodules, etc., and the injection method is correct, basically such symptoms can be judged to be unrelated to insulin injection. The use of insulin for a few days only will not cause the so-called “fattening”. Combined with the fact that you had chest and abdominal fluid some time ago, it is recommended that you go to the hospital to perform ultrasound examinations to clarify the diagnosis, identify the cause, and treat the symptoms or the cause.
