#5 You observe discoloration or swelling in your lips, hands, and feet
Hyponatremia (a condition where you have way too little sodium in your bloodstream) can be developed if you drink too much water. This condition can lead to not only swelling in your lips, hands, or feet but can also cause them to lose their distinctive color. In a lot of bad cases of overhydration, the skin will start to swell overall. In the less severe ones, you may just look swollen and bloated instead.
Overhydration will also make you gain weight suddenly, which is just your body retaining all the excess water in your bloodstream. If you ingest more than ten cups of water daily and you start to see these body parts discolor or start swelling out of the blue, then you should cut back on how much you drink. In a lot of cases, you will see the symptoms slowly disappear.
