Does Walmart have over the counter with fluid pills?

If you mean "water pills" they sell Diurex over the counter.

Before you spend money on something you don't really need, try drinking more water first.

It sounds counterproductive, I know. But here's the deal -

Water retention is actually one of the body's defenses to prevent cell damage due to chronic dehydration. Of all the nutrients that your body gets from food, water is the only one you have to physically consume. Water is the most important resource the body needs to sustain life (and maintain proper health), but most people (adults) lose around 2 quarts of water per day and never replace it properly. And it's when you maintain a water deficit that problems start to happen.

When you don't drink the water you should, the body starts holding onto salt because salt retains water and it's the only option the body has of conserving water to prevent cell damage. This water conservation happens in the area outside the cells because it contains a water/salt mix, and only fresh water can go into the cells. It then filters this water and injects it as fresh water into the dehydrated cells.

This action is a little-known but secondary aspect to high blood pressure. The increased blood pressure is required for the filtration and injection process, This isn't to say that you should have high blood pressure under these conditions, nor is it a prediction of high blood pressure - it all depends on how your body exhibits its various symptoms. If you don't have high blood pressure, chances you won't develop it unless the action of injecting the water into the cells becomes great enough to reveal it.

This may sound confusing to you, and in some respects, the functions of the body are very confusing. Perhaps this is why when doctors explain things to you they use complicated medical jargon so you won't understand.

An easy way to get an overall grasp is to remember that the reason the body is made up of so much water (about 75% on average) is that every function is tied to it. Contrary to the medical beliefs that the functions of the body are controlled through medication, they're actually controlled by water - water is the common denominator to every function and when you maintain low water levels (chronic dehydration) it has an effect on all of those functions.

And here's a surprise that doctors will never reveal - the next most important substance needed by the body is salt. Whenever you lose water you lose salt as well. As mentioned, people don't replace their lost water properly, so they remain in a salt deficit as well. The claims of "getting too much salt from processed foods" is BS. When people develop high blood pressure and it appears that there is too much salt in the body, it's only because the body is dehydrated (lower water levels that affect every function) and consequently, has started retaining salt to protect itself.

Avoiding all water substitutes and increasing the water intake should relieve the water retention. And although not replacing the water coincides with losing salt, do not add more salt to your diet yet. Your body is in a salt retention mode and already has plenty of salt. Once you drink enough water to rehydrate the cells, the excess salt you now have will be flushed out. Then you can increase your salt intake until you reach a balance with your water intake. Unfortunately, there is no way to accurately know how much salt is needed - it's a trial-and-error exercise.

Hope this helps and I hope I didn't lose you on anything.

In some countries, petroleum jelly is sold under the counter in their pharmacies.
