what are water tablets for?

They help remove excess water from your system. The prescription ones basically force you to pee, which dehydrates you and forces your body to leech the water from other parts of the body that have too much. There are natural options that typically help to support lymphatic drainage so your body can naturally move the excess fluid around and can remove the puffiness gently.

It's like the old adage of doing things the easy way or the hard way... you can fight with a child to get something away from them and succeed with a lot of tears and struggle, or you can ask them nicely and get it without the struggle. ;-) Good luck and I hope I helped!

Water tablets is a commonly used, yet not very accurate, term for diuretics.

Diuretics are medicines used to treat a number of medical conditions primarily hypertension, edema (oedema), pulmonary edema, and congestive heart failure. There are essentially three classes of diuretics- thiazide diuretics (eg., hydrochlorothiazide (HCTZ) and chlorothiazide), loop diuretics (eg., furosemide, torsemide, and bumetanide), and potassium-sparing diuretics (eg., spironolactone and amiloride). Certain diuretics may have additional uses such as spironolactone which is often prescribed to women to treat acne, hirsutism (abnormal hair growth), hyperaldosteronism (caused by the overproduction of the hormone aldosterone), among other uses.

The reason diuretics are often called "water tablets" or "water pills" is because, simply put, they remove water from the body by increasing the amount of urine the kidneys produce. As a result they tend to increase urination, people taking certain diuretics in particular need to stay hydrated since they are more likely to become dehydrated.

Diuretics have also been misused to help with weight loss, although the weight diuretics lose is just water which is very easily regained and misusing diuretics for weight loss is very dangerous.
