When to see a doctor
See a doctor urgently if:

- If you have diabetes, heart disease, or high blood pressure
- If it started after you began a new medicine or after a surgery
Diagnosis
Your doctor will talk with you about your symptoms, medical history, and lifestyle. They may also do a physical exam and order simple tests.
Tests that may be done
- Blood test to check testosterone levels
- Blood test for blood sugar (diabetes) and cholesterol
- Urine test
- Ultrasound to check blood flow to the penis
What to expect at your appointment
The doctor may ask personal questions about your sex life, stress, and habits. This is normal. It may take a few visits to find the cause. The important thing is that you are on the right track.
Treatment
Treatment depends on the cause. It often includes healthy lifestyle changes, counseling, and medical options. Most men see improvement when they get the right care.
Self-care at home
- Exercise regularly to improve blood flow
- Quit smoking and limit alcohol
- Manage stress with relaxation or counseling
- Talk openly with your partner
- Get good sleep
Medical treatments
There are several general treatments your doctor may discuss. Some are pills taken before sexual activity. Others are placed in the urethra or injected into the penis. There are also vacuum devices and penile implants. Your doctor will explain the options and help you choose what is best for you. Do not buy any erection pills without a medical evaluation.
When is surgery considered?
Surgery, such as a penile implant, is usually a last resort. It is considered when other treatments have not worked or for men with specific injuries. It is a personal choice made with your doctor.
Living with this condition
Living with sudden ED can be stressful, but it does not have to control your life. Focus on your overall health and talk to your partner about what is happening. You are more than this condition.
Lifestyle tips
- Stay physically active
- Eat a balanced diet with fruits, vegetables, and whole grains
- Keep to a healthy weight
- Avoid smoking and heavy alcohol
- Keep blood pressure, blood sugar, and cholesterol under control
Diet and exercise
A heart-healthy diet and regular exercise like walking, swimming, or cycling can improve blood flow and help with erections. Even 30 minutes a day makes a difference.
Mental health and emotional wellbeing
ED can cause anxiety, depression, and low self-esteem. It can also strain relationships. These feelings are normal. Talk to your doctor about them and consider speaking to a counselor.
Prevention
Many cases of sudden ED can be prevented by a healthy lifestyle — staying active, eating well, not smoking, and managing stress. However, some causes cannot be prevented, such as side effects from a needed medicine or an injury.
Vaccines
There is no vaccine for erectile dysfunction.
Screening programmes
There is no routine screening, but if you have risk factors like diabetes or heart disease, your doctor may check your blood pressure, blood sugar, and cholesterol regularly.
Complications
If left untreated
- ED may not improve on its own
- It can cause stress, anxiety, or depression
- It can damage relationships and self-esteem
- It may hide a serious underlying condition like heart disease or diabetes
Long-term outlook
The outlook is generally very good. Because sudden ED often has a clear trigger, most causes are treatable or reversible. With the right support, the large majority of men recover their confidence and a satisfying sex life.
