Loop diuretics are a type of medication that help the body get rid of excess fluid by increasing urine production. They work by blocking the reabsorption of sodium and chloride in the loop of Henle, a part of the kidney. This action helps lower blood pressure and reduce swelling, making them useful for conditions like heart failure and edema. Common examples of loop diuretics include furosemide and bumetanide. While they are effective, they can also lead to side effects such as dehydration and electrolyte imbalances. Therefore, it's important for patients to be monitored by their healthcare provider while using these medications.
