There are many extra-hepatic manifestations of HCV.
Diabetes is one of them, and uncontrolled diabetes decreases SVR rates, so you need to care.
Common symptoms of diabetes include thirst and the yeast infection thrush.
Thrush can be a white mouth, a sore mouth, a sore back passage, a red rash under the breasts, in the crutch, or on the feet.
Diabetes is quite simply diagnosed with a fasting blood sugar and this can be done in 30 seconds with a finger prick blood sample.
If your blood sugar is over 11 mmol then that's it - you are diabetic. No if's ands buts or maybes. If it's between 7-11 it needs a glucose tolerance test.
If you have diabetes, or develop it on treatment with DAAs then treating it with Metformin is a damn good idea.
Weight loss is known to reduce blood sugar levels in type 2 diabetics, so it is possible for many people to use this as a non-drug method of fixing the disease.
While HCV is a nasty disease so is diabetes so please don't ignore the symptoms. The test is simple and so is the treatment if required.
