Edema or water retention develops once an individual consumes foods that contains large amounts of sodium higher than the intake of water. It is important to note that salt is comprised of 2 essential electrolytes – sodium and chloride. Imbalance in the level of electrolytes can occur if the intake or loss of an electrolyte is excessive. Excess sodium in the body can trigger electrolyte imbalance which cause edema or hypertension.
Close look on edema
Edema develops once excess water builds up mainly between the cells in the tissues of the extremities or in the circulatory system. In severe cases of edema, it can affect the functioning of the heart, kidneys and lungs.
Always bear in mind that edema is simply a symptom which indicates that the body is under stress. Some of the risk factors for edema include high-salt intake, pregnancy, allergies, infection, prolonged period of sitting or standing, physical activity in high temperatures and high blood pressure.
What you need to know about salt
Salt is comprised of 60% chloride and 40% sodium. A teaspoon of salt can provide 2,000 mg of sodium. It is sad to note that many individuals all over the world consume twice this amount on a daily basis.
Some cases of deaths yearly are linked to the consumption of high amounts of salt. With this in mind, avoid the intake of salt especially foods that contain added salt such as pretzels and potato chips.
What is the role of sodium?
Opposing a general belief, sodium and salt are not the same. While salt is the main source of sodium, sodium is present in almost all foods. The everyday consumption of sodium is needed to ensure sufficient bodily function.
Sodium is responsible for regulation of the water balance in the body. On the other hand, sodium can also lead to dehydration. Once an individual consumes large amounts of sodium, the body starts to retain onto the current water supply which contributes to edema. It is recommended to consume between 1,500 – 2,300 mg of sodium on a daily basis.
What is the role of water?
Many individuals are chronically dehydrated. It is vital to drink sufficient amounts of water such as eight 8-oz. servings every day to help relieve water retention or edema.
The intake of excess sodium can increase the need of the body for water since surplus water helps dilute the sodium. In case not enough water is consumed and the overall water balance in the body drops, the body starts to retain the current water supply. As a result, water builds up in the tissues of the body and quite evident in the feet, arms, hands and ankles.
