Puffiness in your feet, legs and ankles, as well as your face and hands, can be a sign of water retention, also known as edema. Water retention can occur for a number of reasons, but high caffeine and sodium consumption are two of the more common causes. Sodas can contain both sodium and caffeine, and regular consumption of soda, especially in high quantities, could lead to water retention.
While most cases of water retention can be treated at home, severe cases or regular instances of water retention should receive medical care.
Caffeine in Soda
Caffeine in Tea and Soda
Caffeine is a natural diuretic, which causes your body to release fluids. This can actually lead to water retention, as your body tries to hold onto the remaining water in you system as an attempt to reduce the risk of dehydration. According to the NYU Langone Medical Center, popular name-brand sodas, such as Dr. Pepper and Coca-Cola, can contain between 35 and 47 milligrams of caffeine per 12-ounce serving.
Despite their sweet taste, sodas contain a surprising amount of sodium. Sodium makes you feel thirstier, and after one soda, it may be difficult to stop. Sodas can contain between 40 to 70 milligrams of sodium per 12 ounce can. A single can of soda will provide only a small percentage of the recommended upper limit of sodium consumption, but this percentage is quite high considering the small size of a can of soda. The recommended upper limit for sodium is 2,400 milligrams, or 1,500 milligrams for those over 50, who have a history of heart disease or who are African American.

Preventing Water Retention
What Are the Benefits of Not Drinking Soda?
While a single can of soda is unlikely to cause water retention, drinking a lot of soda regularly, or in combination with other factors such as hot weather, can lead to puffiness. To prevent or reduce the symptoms of water retention, make sure you stay well-hydrated. According to MedlinePlus, the general recommendation is to drink at least six to eight 8-ounce glasses of water per day, and more if you are feeling dehydrated, are exposed to hot weather or have participated in hard physical activity 35. Choose low-sodium, caffeine-free drinks, ideally water, although beverages such as herbal teas can also be healthy choices.
