Erectile dysfunction: Causes, symptoms and treatment options explained
By Valerian Khakayi, July 22, 2026Erectile dysfunction is more common than many people realise, yet it remains one of the least talked-about men’s health conditions.
While occasional difficulty getting or maintaining an erection is normal, persistent problems can affect confidence, relationships and overall wellbeing. In many cases, erectile dysfunction is also an early warning sign of an underlying health condition that should not be ignored.
According to the Cleveland Clinic, erectile dysfunction is one of the most common sexual health conditions affecting men, particularly as they get older.
However, it is not an inevitable part of ageing, and, in many cases, it can be treated successfully once the underlying cause is identified.
What causes erectile dysfunction?
Erectile dysfunction can result from physical, psychological or lifestyle-related factors. In many men, more than one factor contributes to the condition.
According to the Cleveland Clinic, erectile dysfunction can be caused by a combination of physical, psychological and lifestyle factors. Common causes include diabetes, high blood pressure, high cholesterol, heart and blood vessel disease, low testosterone levels, kidney disease, nerve disorders or injuries, and side effects of certain medications.
Lifestyle habits such as smoking, excessive alcohol consumption and drug use can also increase the risk. In addition, obesity, stress, anxiety, depression, relationship problems and performance anxiety can all contribute to erectile dysfunction.
“There are many different causes, which may include conditions that affect your blood vessels, neurological conditions, mental health conditions and injuries,” Cleveland Clinic stated.
Who can be affected?
Although erectile dysfunction becomes more common with age, it can affect men of all ages.
However, the risk increases in men aged 40 and above, as well as those living with diabetes, obesity, depression or inactive lifestyles. Smokers and men with cardiovascular disease are also more likely to develop the condition.
Symptoms of erectile dysfunction
The main symptom of erectile dysfunction is the inability to get or maintain an erection firm enough for sexual activity. Some men may have difficulty getting an erection, while others may struggle to maintain one during intimacy or find that their erections are not firm enough for intercourse.
In some cases, men may need excessive stimulation to achieve or maintain an erection and may experience reduced confidence or anxiety about their sexual performance.
While occasional erection problems are common and usually not a cause for concern, persistent symptoms that occur repeatedly or last for several weeks or months should be assessed by a healthcare provider.
How is it diagnosed?
According to the Cleveland Clinic, a healthcare provider will usually begin by discussing your medical history, symptoms and lifestyle before carrying out a physical examination.
Depending on the suspected cause, blood tests, urine tests, hormone tests or specialised imaging may be recommended to identify underlying medical conditions.
Treatment options
Treatment for erectile dysfunction depends on its underlying cause. According to the Cleveland Clinic, many men can improve their condition by making healthy lifestyle changes, such as exercising regularly, maintaining a healthy weight, quitting smoking and limiting alcohol intake.
Managing medical conditions like diabetes and high blood pressure can also help. For men whose condition is linked to stress, anxiety or depression, counselling or therapy may be recommended.
Healthcare providers may also prescribe oral medications, testosterone replacement therapy for those with low testosterone levels, or other treatments such as vacuum erection devices, penile injections or surgery in certain cases.
Can it be prevented?
Although not every case of erectile dysfunction can be prevented, adopting a healthy lifestyle can significantly reduce the risk.
Experts recommend exercising regularly, eating a balanced diet, maintaining a healthy weight, and keeping conditions such as high blood pressure, high cholesterol and diabetes under control.
Quitting smoking, limiting alcohol intake, getting enough sleep and managing stress can also help improve overall health and lower the likelihood of developing erectile dysfunction.
