In short: Eating some sugar does not directly cause erectile dysfunction. But a diet high in added sugar contributes to weight gain, insulin resistance, prediabetes and type 2 diabetes, which damage the blood vessels and nerves needed for erections and can lower testosterone. Men with diabetes are much more likely to have ED, and many do not know they have high blood sugar.

How high blood sugar affects erections

  • Blood vessel damage: high glucose harms the vessel lining and reduces nitric oxide.
  • Nerve damage: diabetes can damage the nerves that trigger erections.
  • Lower testosterone: insulin resistance and excess weight are linked with lower testosterone.
  • Inflammation: high sugar intake promotes inflammation.

Prediabetes and ED

Erection problems can appear before diabetes is diagnosed. Many South African men have undiagnosed prediabetes or diabetes. Signs include thirst, frequent urination, tiredness and slow-healing wounds. See frequent urination in men.

Where hidden sugar comes from

  • Fizzy drinks, energy drinks and fruit juices
  • Sweetened coffee drinks
  • Sweets, biscuits and pastries
  • White bread, refined maize meal and sugary cereals
  • Sauces and flavoured yoghurts

Natural steps that help

Swap sugary drinks

Choose water, sparkling water or unsweetened rooibos. See rooibos tea benefits for men.

Choose whole grains and fibre

Oats, brown rice, legumes and vegetables slow sugar absorption. See okra benefits for men.

Move after meals

A 10 to 15-minute walk after eating lowers blood sugar spikes. See exercises for erectile dysfunction.

Lose excess weight

See weight loss and erectile dysfunction.

Sleep well

Poor sleep worsens insulin resistance.

Spices and foods that may help

Cinnamon and fenugreek may modestly support blood sugar control. See cinnamon benefits for men.

Get your blood sugar checked

If you have erection problems, especially over 40 or with a family history of diabetes, ask an appropriately registered medical professional or pharmacy for a blood sugar test.

Private self-check: 5 quick questions

Answer these honestly before you try anything new or book. They help you describe what is happening and get more from your first consultation.

  1. How often can you get and keep an erection firm enough for sex: almost always, most of the time, sometimes, or rarely?
  2. Do you still notice morning or night-time erections?
  3. Have stress, poor sleep, alcohol, smoking or long hours increased recently?
  4. Do you take medicine for blood pressure, the heart, diabetes or mood?
  5. Has your interest in sex dropped noticeably over the past year?

If you answered “sometimes” or “rarely” to the first question, a consultation is a sensible next step. Morning erections that still happen are often a reassuring sign that lifestyle, stress or confidence are playing a part, which natural support can address well. A yes to question four means any remedy needs checking for interactions first.

What happens at your first consultation

  1. Walk in or book online, call +27 10 205 9855 or WhatsApp +27 81 823 1313. In Gauteng, walk in at 199 Vanessa Street, Buccleuch, Sandton, where parking is available. Outside Gauteng, choose a confidential phone or video consultation. Enquiries are answered 24/7.
  2. Talk privately with a naturopath about your symptoms, health history, lifestyle and goals.
  3. Receive a personalised natural plan, with any remedy costs confirmed upfront.
  4. Follow up in person or remotely so your progress is reviewed and your plan adjusted.

Your health and safety

Our naturopaths use natural remedies and lifestyle support, and always check your health history and current medicines first. If anything needs medical attention we tell you honestly and refer you to an appropriately registered medical professional. Avoid unregistered “enhancement” products sold online or at markets, as SAHPRA has warned that some contain hidden ingredients.

Seek urgent medical care for chest pain, an erection lasting more than four hours, sudden weakness or other sudden symptoms.

Consultation price

A consultation is R2,500, in person or remote, and your naturopath confirms any further costs before you go ahead. See our men’s clinic prices for details.
