In treatment of hypertension, depending on the specific case, the doctor prescribed diuretics. In patients with hypertension, the amount of salt and excess water in the body causes the artery to be under more pressure. Diuretics affect the kidneys to increase the amount of salt and waste water from the body through the urinary tract. In addition, the diuretic also helps the artery wall more elastic, blood circulation more easily. Thanks to these two factors, the pressure on the arteries will decrease significantly, bringing the blood pressure level to the safety threshold. Some studies have also shown that diuretics support very well for other hypertensive drugs such as beta blockers, angiotensin converting enzyme inhibitors, etc., which overcome the side effects of water retention in the body. When taking these medications. Thus, diuretics are often prescribed as first choice or as a component in fixed-dose combination therapy to help patients control their blood pressure most effectively.
Thiazides (including furosemide) were first used to treat mild hypertension and other cardiovascular problems associated with blood pressure. The drug reduces the levels of Na + into blood vessels, reducing the sensitivity of the arteries to cathecolamin, thereby reducing the resistance of the circulatory system, but should be treated for weeks to see the effect. In addition to treating hypertension, diuretics are also used in the treatment of heart failure, pulmonary edema, kidney disease, nephrotic syndrome.
However, the side effects of the drug can cause: frequent urination, dehydration (if drinking water does not reduce this condition, the patient feels thirsty, dry mouth, dark yellow urine, constipation, you should go to the doctor for examination), hyperglycemia, loss of potassium (good minerals help support normal blood pressure), headaches, cramps, dizziness, fatigue ... When symptoms appear on the patient Inform your doctor about this in order to be dealt with promptly and appropriately.
