痛風又稱為代謝性關節炎，這個疾病近年越來越年輕化，而且越趨普及，患者病發時會感到關節位置非常的痛，而且加上風吹會加劇疼痛，好多人病發都會用止痛藥舒緩，疼痛感消化後就沒有再理會。不過其實患有痛風日子越久，會直接增加泌尿道結石以及腎臟病的機率。台灣節目《健康2.0》就請來江坤俊醫師，為大家解答痛風成因以及4個預防方法。
痛風的主要成因是血液中尿酸沉積於關節中，導致發炎疼痛。而尿酸會沉積在關節裡的原因是血液中的尿酸濃度過高。當尿酸沉積在關節，就會引發痛風，關節會紅腫熱痛。
江醫師解釋，尿酸除了會沉積在關節裡，也會沉積在腎臟，影響腎臟功能。如果尿酸被腎臟排出到尿液裡面，尿液中的尿酸濃度過高就會產生泌尿道結石。因此痛風會直接增加泌尿道結石以及腎臟病的機率。
血液中尿酸變高的原因有四，第一個原因就是吃太多高普林(Purine)食物，包括海鮮、肉、火鍋濃湯。第二個原因就是壓力過大或過份激烈運動，當人感到壓力或激烈運動的時候，細胞中DNA崩解的速度會加快，崩解後會變成一種普林，普林經身體代謝之後就會變成尿酸。第三個原因是肥胖，肥胖會影響體內尿酸的代謝，令尿酸容易變高。最後是飲酒，飲酒之後體內會產生乳酸，影響尿酸的代謝，減慢尿酸排出。
江醫師建議想遠離痛風就要從以下四點著手︰
