Final answer:
Thiazides can precipitate gout by increasing uric acid levels in the blood. Gout is a painful condition caused by the deposition of uric acid crystals in joints and soft tissues. Uricosuric drugs and dietary choices can help manage and reduce the risk of gout.
Step-by-step explanation:
Thiazides are a class of drugs that can potentially precipitate gout by increasing the levels of uric acid in the blood. When uric acid levels exceed 7 mg/100 ml in the blood plasma, this can lead to the precipitation of uric acid as sodium ureate crystals. These crystals can then get deposited in soft tissues, including joints and tendons, causing the painful condition known as gout. Conditions such as excessive intake of fructose can also raise the chances of developing gout. In contrast, gout can be controlled using uricosuric drugs like salicylates, which increase the excretion of uric acid in urine, thereby decreasing its re-absorption.
It is also important for individuals susceptible to gout to make dietary choices that reduce the amount of nitrogenous bases, like opting to avoid food and drinks high in purine-like compounds. For example, tea, coffee, and chocolate containing xanthines should be avoided to help reduce the risk of gout and kidney stones.
