Many men at some time of their life will have problems getting an erection or keeping an erection. This problem is more common with increasing age.
There are many possible causes such as:
Being very overweight
Having diabetes
High blood pressure or high cholesterol
Depression (if you think you may be depressed, see your doctor)
Smoking cigarettes
Medicines (talk to your doctor or pharmacist about whether this could relate to your medicines, do not stop taking your regular medicine without their advice)
Use of recreational (street) drugs
Relationship difficulties (you may need relationship counselling)
Being tired or stressed
Drinking too much alcohol
Performance Anxiety
Erectile dysfunction (ED) can sometimes be caused by an important health problem, all men with erection problems should inform their doctor that it is occurring. Erection problems can also occur from a build-up of fatty deposits in the blood vessels, the same problem that causes heart trouble.
