Did you know that one in 10 people will develop kidney stones in their lifetime? These tiny, hard deposits can cause intense pain that sends even the toughest individuals to the emergency room.
Kidney stones form when minerals and waste in urine become too dense. Normally, these substances are flushed out with the urine. However, if there’s not enough water in the body, or the levels of these substances are too high, they can cluster together and form crystals. Over time, these crystals can grow into hard lumps that may block the flow of urine. The primary symptom is sudden, severe pain in the back or side, sometimes accompanied by nausea, vomiting or blood in the urine.
Dehydration is a major risk factor for stone formation. When the body lacks adequate hydration, urine becomes concentrated and stones form more easily. This risk intensifies during hot weather or periods of heavy sweating if you don’t replace lost fluids. Additionally, a diet high in salt, animal protein or sugar—as well as a family history of kidney stones—can increase your risk.

Prevention strategies are remarkably straightforward and highly effective. Drink sufficient water every day to keep your urine light yellow and clear. This helps remove extra minerals before they form stones. Certain foods should be consumed in moderation, including salty processed foods, red meat, and foods rich in oxalates like spinach, chocolate, and nuts. Contrary to popular belief, dietary calcium actually helps prevent stones by binding with oxalates in your gut and stopping them from reaching your urine. By making simple lifestyle modifications, you can effectively keep kidney stones at bay.
你知道每十個人就有一人一生中會罹患腎結石嗎？這些微小而堅硬的沉積物會引起劇烈疼痛，即使是最堅強的人也可能因此被送到急診室。
腎結石是當尿液中的礦物質和廢物變得過於濃縮時形成的。通常，這些物質會隨著尿液被沖洗出去。然而，如果體內水分不足，或這些物質的濃度過高，它們就會聚集在一起形成結晶體。隨著時間推移，這些結晶體會長成硬塊，可能會阻塞尿液的流動。主要症狀是背部或側面突然劇烈疼痛，有時伴隨噁心、嘔吐或血尿。
脫水是結石形成的主要風險因素。當身體缺乏足夠的水分時，尿液會變得濃縮，結石更容易形成。如果你在炎熱天氣或大量出汗期間沒有補充失去的液體，這種風險會加劇。此外，高鹽、高動物蛋白質或高糖的飲食──以及腎結石家族史──都會增加你的風險。
預防策略非常簡單且高度有效。每天喝足夠的水，保持尿液呈淡黃色且清澈。這有助於在多餘的礦物質形成結石之前將其排出。某些食物應該適量食用，包含高鹽加工食品、紅肉，以及富含草酸鹽的食物，如菠菜、巧克力和堅果。與普遍觀念相反，膳食鈣質實際上有助於預防結石，因為它會在你的腸道中與草酸鹽結合，並阻止它們進入尿液。透過簡單的生活方式改變，你可以有效地預防腎結石。

The subject of placebos has been fascinating scientists and medical professionals for decades. The word placebo comes from Latin and means “I shall please.” The concept of the placebo effect refers to the phenomenon in which treatments or procedures produce positive outcomes merely because individuals believe they will work. __1__ During medicine trials, researchers often include a “placebo group” as a control to measure the true efficacy of the medication being tested. While one group receives actual drugs, the placebo group is given an inert substance, such as a sugar pill. To ensure unbiased results, participants in the placebo
