Erectile dysfunction (ED) is a term used to describe persistently being unable to get or maintain an erection to achieve satisfactory sexual activity and it affects approximately 50% of men during their lifetime. ED used to be considered a problem of older age but it affects all age groups and is increasingly common in younger men.
ED is often a symptom of other health issues and is commonly experienced by people who have some underlying health problems, the most common being heart disease, type 2 diabetes, high blood pressure, high cholesterol, depression and hormonal imbalances. Men who smoke are at higher risk than non-smokers of experiencing erectile problems. The main underlying physical factor is reduced flexibility and blood flow in the arteries.
Research surrounding the effects of drinking alcohol on erectile function suggests that moderate alcohol consumption (14 units a week) does not have a negative impact. Higher alcohol intakes, and/or increased frequency of alcohol drinking are thought to increase the risk of experiencing ED, and findings suggest that the more alcohol you drink the bigger the impact on ED.
ED is more common in men who are overweight, obese or have a high waist measurement. Losing weight and/or reducing your waist size has been found to help reduce ED.
Recommended eating guides for weight loss
One small study found that weight loss may help to preserve erectile function and prevent the worsening of ED. Another found that introducing lifestyle changes including a combination of losing weight and increasing physical activity led to an improvement in erectile function.
The best weight loss diet to follow to improve erectile function if you are overweight is the Mediterranean diet. Eating a Mediterranean diet has been linked with having more flexible arteries and heart health and can support healthy weight loss and has been found to reduce erectile dysfunction. The most important factor though is to find a dietary pattern that you are happy to follow that can help you lose weight.
Boosting intake of arginine (an amino acid found in many protein-rich foods) may help to improve circulation, a factor in ED - a Mediterranean diet is naturally rich in arginine. Nitric oxide helps you get an erection by increasing blood flow to your penis.

Include colour in your diet from a variety of vegetables and fruit - aiming to eat the rainbow across the week - when you shop head to the vegetable aisle and see how many different colours you can add to your basket. All of these foods are rich in antioxidants which have been shown to improve blood flow and erectile function. Dark chocolate is rich in antioxidants so we would recommend you enjoy a couple of squares every day.
Measuring and reducing your waist if your waist is bigger than the recommended size is a simple way of monitoring your health. Reducing your waist circumference through following a healthy diet and increasing physical activity may help with erectile function.
How to measure your waist
Diet has a profound impact on the type of bacteria that live in our guts and the type of bacteria that populates each person's gut is very much influenced by what they regularly eat and drink. Many other factors including stress and low-grade inflammation have also been found to influence the gut microbiome.

Research suggests that being physically active is a vital part of preventing ED. Studies into physical activity and ED have found that all activities including walking, running, swimming, and cycling are beneficial and that the more active a person is the lower their risk of experiencing ED and increased activity may help to reverse it.
Having strong pelvic floor muscles may help you to achieve an erection. The pelvic floor is a muscular band that stretches from the tailbone to the pubic bone. Several factors can lead to a weakened pelvic floor including:
To improve a weakened pelvic floor aim to make doing pelvic floor exercises part of your daily routine.
An easy way to work out where your pelvic floor is - is to stop your flow of urine when peeing, or to stop yourself when passing wind.
Now you have found your pelvic floor, aim to tighten these muscles on and off throughout the day, the great news is you can do these exercises anywhere. Aim to tighten and hold your pelvic floor muscles for a count of three and then relax these muscles slowly - aim to build up to three sets across the day - aiming for about 10 sets once your muscles start to strengthen.
Smoking worsens ED by affecting blood vessels. The more exposure to smoking, the more cigarettes smoked and the number of years as a smoker affects how severely blood vessels are impacted - Some research showed that stopping smoking can improve erectile function and the sooner you stop smoking the better the outcome.
Talking to your partner is an important step in reducing the emotional impact of ED, this may also help to alleviate any worry that you are experiencing. Open communication can help to build trust and understanding in a relationship which can, in turn, support you to overcome ED.
There are two separate types of stress that can be a factor in erectile dysfunction.
Blood flow to the penis that helps to create an erection can be affected by emotional stress and anxiety - this can become a vicious cycle as experiencing ED may increase feelings of emotional stress and anxiety. Identifying and managing your stressors can be helpful.
Oxidative stress is a natural part of the ageing process. Some lifestyle factors can increase the likelihood of this being a factor in ED. These include being overweight or obese, smoking, and high alcohol intake. Increasing dietary sources of antioxidants (naturally bright or dark coloured foods) and addressing the triggering factors can help to reduce oxidative stress.
