Can drinking alchohol cause psoriasis?
In the case of psoriasis, moderate to heavy consumption of alcohol-containing drinks such as beer, rum, and cocktails, can trigger the initial development of psoriasis and may trigger future flare-ups. Not much is said regarding the mechanism of action of alcohol in its role in triggering psoriasis, but it is most likely attributed to a person’s level of alcohol intolerance in which a low level of tolerance can produce an allergic reaction, and alcohol’s immunosuppressant properties which can make a person more susceptible to infection. Both allergic reactions and infections are said to be triggers of psoriasis in many people, therefore consumption of alcohol can contribute to the development of psoriasis. Alcohol also acts as a vasodilator, which allows more white blood cells, including T cells to pass through the tissues, which may worsen the autoimmune reaction of psoriasis. It is also a potent diuretic, and excessive drinking can lead to frequent urination and vomiting, with can cause dehydration and loss of electrolytes. Dehydration can affect the skin and worsen psoriasis by making the skin more tight, irritated, and more likely to crack and bleed especially upon scratching.
Intake of alcohol in excessive amounts is detrimental to health in general, although there have been studies suggesting drinking small amounts of alcohol-containing drinks, particularly wine, can give cardiovascular benefits and may have anti-ageing properties due to the presence of antioxidants.
