Men with an enlarged prostate (benign prostatic hyperplasia, or BPH) should avoid caffeine, alcohol, decongestants and antihistamines, all of which can worsen urinary symptoms. Spicy food, prolonged sitting, heavy lifting and drinking fluids late at night also aggravate the prostate. BPH affects more than half of men over 50 in the UK and causes symptoms including a weak urine stream, frequent urination and the need to get up at night. While BPH is not cancer, it can significantly affect daily life. The good news is that most symptoms can be managed well with the right lifestyle adjustments and, where needed, specialist treatment.

1. Caffeine and alcohol
Both caffeine and alcohol act as diuretics, which means they can increase urine production. This can exacerbate the frequent need to urinate, one of the hallmark symptoms of prostate enlargement. Caffeine, found in coffee, tea, and soft drinks, can also irritate the bladder, leading to an increased sense of urgency.
Similarly, alcohol can have a similar effect by stimulating your kidneys to produce more urine. In the UK, around 40% of men aged 50 and over report frequent urination at night, and cutting back on these beverages can make a big difference in managing these symptoms.
2. Spicy foods
Spicy foods may add flavour to your meals, but they can wreak havoc on your bladder. Chilli peppers, curries, and other spicy dishes can irritate the bladder lining, making it harder to control urination.
While there’s no need to completely give up on your favourite dishes, you might want to moderate your intake. Many men with BPH find that limiting spicy foods helps to reduce their symptoms and improves bladder control.
3. Dehydration
You might think that drinking less will help reduce the need to urinate, but dehydration can actually make symptoms of BPH worse. When your body is dehydrated, urine becomes more concentrated, which irritates the bladder and can increase the urgency to urinate.
It’s important to drink enough water throughout the day, but be mindful of your fluid intake in the evening to avoid nighttime bathroom trips.
4. Over-the-counter decongestants
If you’re suffering from a cold, you might reach for a decongestant, but it’s important to be cautious if you have prostate enlargement.
Decongestants containing pseudoephedrine or phenylephrine can constrict the muscles around the urethra, making it even more difficult to urinate.
These medications can worsen symptoms such as a weak urine stream or difficulty starting to urinate. Instead, opt for non-decongestant cold treatments and always check with your doctor before taking any over-the-counter medications.
5. Antihistamines
Similar to decongestants, antihistamines, often taken for allergies, can also contribute to urinary retention. Antihistamines work by relaxing the muscles in your bladder, which can lead to difficulty in emptying it completely.
If you’re dealing with both allergies and BPH, speak to your GP about alternative treatments that won’t exacerbate your symptoms. This is particularly important during the allergy season when antihistamines may become a regular part of your routine.
6. Sitting for long periods
Spending too much time sitting can put pressure on your prostate, potentially worsening symptoms of BPH. For men who work in office settings or lead sedentary lifestyles, this can be particularly problematic.
In the UK, 81% of office workers sit at a desk for four to nine hours each day, increasing their risk of discomfort due to prolonged sitting. Make it a habit to stand up, stretch, and move around every hour to alleviate pressure on your prostate. Regular physical activity has also been shown to help reduce BPH symptoms over time.
7. Ignoring the urge to urinate
One of the most common symptoms of prostate enlargement is the frequent need to urinate. While it might be tempting to hold it in, especially if you’re busy or out in public, this can actually worsen your symptoms.
Ignoring the urge to urinate can stretch your bladder muscles, leading to weakened bladder function in the long run. It’s important to listen to your body and use the restroom when you feel the urge, as holding it in can lead to more serious issues like urinary tract infections.
8. Heavy lifting
Heavy lifting can put strain on your pelvic muscles, increasing pressure on your bladder and prostate. This can make it harder to urinate and worsen symptoms of BPH. If your job or exercise routine involves lifting, try to be mindful of how much strain you’re placing on your body.
Consider lightening the load or using proper lifting techniques to reduce the pressure on your pelvic region. If you notice that lifting consistently worsens your symptoms, it may be time to consult a healthcare professional for advice on managing physical activities.
9. Excessive fluid intake before bed
Drinking too much liquid, especially in the evening, can lead to multiple trips to the bathroom during the night. This is a common complaint among men with BPH.
To help mitigate this, try to limit your fluid intake two hours before bedtime. If you’re taking medications that require water, ensure you’re balancing your daily intake throughout the day rather than just before bed.
10. Stress
Stress can have a direct impact on your bladder function and BPH symptoms. When you’re stressed, your body releases hormones that can tighten the muscles around the bladder, leading to increased urgency and frequency of urination.
Stress can cause the muscles around your prostate to contract, exacerbating symptoms. Practising stress-reducing techniques such as deep breathing, meditation, or yoga can help you manage stress and reduce the impact it has on your prostate health.
Final notes
Prostate enlargement is a common issue that many men face as they age, but it doesn’t have to drastically affect your quality of life. By making small adjustments as stated above, you can better manage your symptoms.

Frequently Asked Questions
What makes prostate enlargement worse?
Caffeine, alcohol, spicy foods, over-the-counter decongestants and antihistamines are the most common triggers. Sitting for long periods, heavy lifting, delaying urination, drinking large amounts before bed and chronic stress can also worsen symptoms. Keeping a symptom diary can help you identify your personal triggers.
Can an enlarged prostate be treated without surgery?
Yes. Many men manage BPH successfully without surgery. Lifestyle changes, pelvic floor exercises and prescribed medication (including alpha-blockers and 5-alpha-reductase inhibitors) help the majority of patients. Surgery is considered when symptoms are severe, when medication has not worked, or when complications such as recurrent infections or bladder damage arise.
What foods should I avoid with an enlarged prostate?
There is no definitive prostate diet, but many men find that reducing caffeine, alcohol, red meat and spicy food helps ease urinary symptoms. Staying well hydrated through the day while reducing fluids in the evening is generally beneficial. Processed foods high in saturated fat are also worth limiting.
How do I know if my prostate symptoms are getting worse?
Signs of worsening BPH include a weaker urine stream, a longer wait before urine starts, more frequent trips to the toilet (especially at night), a feeling that the bladder is not emptying fully, or blood in the urine. If you notice any of these changes, a specialist review is advisable.
Is prostate enlargement the same as prostate cancer?
No. Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate. Having BPH does not mean you have or will develop prostate cancer. However, the two conditions can coexist, which is why a proper clinical assessment, including a PSA test where appropriate, is recommended for men with significant symptoms.
When should I see a specialist about an enlarged prostate?
See a specialist if symptoms are affecting your sleep or daily routine, if you notice blood in your urine, if you have difficulty emptying your bladder, or if you have a family history of prostate cancer. A consultant urologist can carry out a thorough assessment, arrange relevant tests and advise on the most appropriate treatment.
