I would suggest Phosphodiesterase-5 inhibitors like Sildenafil or Tadalafilfor the treatment of erectile dysfunction. It should be taken 2 hours prior to sex. Generally it is a safe medication, however it can cause headache, stuffy nose. Nausea, stomach discomfort and visual disturbances. These are prescription medicines, and you need to consult a doctor or psychiatrist or sexologist for the prescription. Since your blood glucose appears to be high, you are advised to consult your treating doctor for certain lab tests such as fasting and postprandial blood glucose, HbA1c, urinalysis, ECG, etc/You also need to have certain lifestyle changes such as:1) Regular exercise for 45 minutes followed by meditation for 1/2 an hour in the morning. 2) Take high protein diet rich in vegetables and fruits and Vitamins A, C, D, E. and Zinc 3)Take anti oxidants like Almonds 5-6 every day. 4) Avoid alcohol and smoking. Hope the advice given would be beneficial. </s>
