Psoriasis in a person with diabetes and high blood pressure requires careful treatment, as some psoriasis medicines can affect blood sugar, blood pressure, liver function, or increase the risk of infection. Treatment usually depends on how severe the psoriasis is, which body areas are involved, and whether you have joint pain or other medical problems. Doctors commonly use moisturisers, medicated creams, vitamin D?based creams, or other anti-inflammatory treatments for mild cases, while moderate or severe psoriasis may require tablets, injections, or light therapy under specialist supervision. Avoid using strong steroid creams for a long time without medical advice, especially if blood sugar is not well controlled. Keeping diabetes and blood pressure under control can also help reduce psoriasis flare-ups. Try to reduce stress, avoid smoking and alcohol, maintain a healthy weight, and keep the skin moisturised regularly. Please consult a dermatologist for proper evaluation because treatment should be selected carefully to avoid worsening diabetes or hypertension and to choose the safest long-term option for you.
