One of the best-established effects of excessive sodium intake is an increased risk of high blood pressure (hypertension).
Too much sodium can cause the body to retain extra water, increasing the volume of blood circulating through the blood vessels. Over time, this places additional strain on the heart and arteries.
2. Increased Risk of Heart Disease and Stroke
High blood pressure is a major risk factor for:
- Heart attack
- Stroke
- Heart failure
Reducing sodium intake can help lower blood pressure in many individuals, particularly those who are salt-sensitive.
3. Kidney Strain
The kidneys help regulate sodium levels in the body. Consistently consuming too much salt forces them to work harder, which may contribute to kidney problems over time, especially in people with existing kidney disease.
4. Water Retention and Bloating
Eating a salty meal may cause your body to hold onto extra fluid, leading to:
- Swollen fingers or ankles
- Puffiness
- Temporary weight gain
- Feeling bloated
These effects are usually temporary but can be uncomfortable.
