For patients with chronic plaque psoriasis, several lifestyle modifications can be recommended to help improve their condition and reduce the risk of exacerbations ,. These include:

  • Smoking cessation: Advise patients to stop smoking if appropriate ,.
  • Alcohol consumption: Encourage patients to drink alcohol within recommended limits ,.
  • Weight management: Recommend weight loss for patients who are overweight or obese ,. Low-quality evidence suggests that obese individuals may experience a greater reduction in psoriasis severity with strict caloric restriction . Dietary intervention in obese patients with psoriasis has been shown to improve dermatology quality-of-life scores and reduce BMI . A dietary intervention combined with an exercise programme may also improve psoriasis severity, though results are inconclusive .
  • Stress and mental well-being: Assess for and manage associated stress, distress, anxiety, and/or depression ,.
  • Physical activity: Offer preventative advice and healthy lifestyle information, including support for increased physical activity .

This lifestyle advice should be tailored to the individual's needs and circumstances .
