Sodium bicarbonate can be drunk and is commercially available in sodium bicarbonate water, also known as seltzer water. Sodium bicarbonate tablets are used orally mainly for hyperacidity of the stomach and in urology mainly for alkalinizing urine, targeting the prevention of uric acid stones and cystine stones, by alkalinizing the urine to inhibit stone formation. In addition, alkalinization of urine with low concentration can also be applied to patients with lower urinary tract infections, the main purpose of which is to reduce bladder irritation symptoms and improve the discomfort of urinary frequency and urgency and pain. Therefore, sodium bicarbonate can be used not only as a medicine but also as a drink, but it should be noted that for some people, such as pregnant women, people with renal insufficiency and children, oral consumption needs to be cautious.
