Alcohol consumption can cause capillary dilation and congestion and increased blood flow, resulting in redness of the palms of the hands, which may be accompanied by facial redness. However, this redness is temporary. If the redness persists, with symptoms such as hives, itchy skin and throat discomfort, you should be alerted to the possibility of an alcohol allergy and seek prompt medical attention for the relevant treatment. In addition, long-term alcohol consumption may affect liver function. If you experience persistent redness in the palms of your hands after frequent or heavy drinking, with symptoms such as weakness, yellowing of the skin and sclera, or loss of appetite, you should seek prompt medical attention for relevant investigations to determine whether there is any liver pathology.
