  • Signs: Muscle weakness, irregular heartbeat.
  • Calcium Disturbance: Altered calcium levels can impact bone health and blood clotting.
  • Manifestations: Osteoporosis, easy bruising.

Hyponatremia: Water Intoxication

Ingesting too much water can lead to a dangerous condition known as water intoxication, also called hyponatremia. When you drink excessive amounts of water, it dilutes the sodium levels in your blood. Sodium plays a crucial role in maintaining the balance of fluids in and around your cells. With low sodium levels, your body's water levels rise, causing your cells to swell. This swelling can lead to various symptoms like nausea, headaches, confusion, and in severe cases, seizures and coma.

Hyponatremia is especially risky during intense physical activities like marathons, where some individuals tend to overhydrate without replacing lost electrolytes adequately. To prevent water intoxication, it's essential to listen to your body's signals and drink water when you're thirsty, rather than forcing excessive intake. If you suspect hyponatremia, seek medical help immediately. Remember, balance is key – stay hydrated, but do so wisely to keep your sodium levels in check and your body functioning optimally.

Effects on Kidneys and Urinary System
