Diseases Due to Deficiency of Water:
| Deficiency Disease | Symptoms | Cause | Function of Water | Sources |
|---|---|---|---|---|
| Dehydration | Dry mouth, dizziness, fatigue, dark urine, confusion | Insufficient water intake, excessive sweating, diarrhea, or vomiting | Water is essential for maintaining body temperature, digestion, and nutrient transport. It also helps in the removal of waste from the body. | Drinking water, fruits (watermelon, oranges), vegetables (cucumbers, tomatoes), milk, soups, and broths. |
| Kidney Stones | Severe pain in the lower back, nausea, vomiting, blood in urine | Chronic dehydration leads to concentrated urine, allowing minerals to crystallize and form stones. | Water dilutes urine, preventing the formation of kidney stones. | Water, herbal teas, fruits with high water content (e.g., melons), and water-rich foods like cucumbers and celery. |
| Constipation | Hard, dry stools, bloating, abdominal pain | Lack of water intake leads to dry stools, making bowel movements difficult. | Water helps soften stools and supports smooth digestion. | Water, fruits, and vegetables (fiber-rich foods combined with water help digestion). |
| Urinary Tract Infections (UTIs) | Painful urination, frequent urge to urinate, cloudy or strong-smelling urine | Insufficient water intake allows bacteria to build up in the urinary tract. | Water flushes out toxins and bacteria from the urinary system. | Water, cranberry juice (helps prevent UTIs), fruits like oranges and water-rich vegetables. |
| Heat Stroke | High body temperature, confusion, nausea, rapid heartbeat | Severe dehydration and prolonged exposure to heat without sufficient water intake. | Water helps regulate body temperature and prevents overheating. | Water, electrolyte drinks, water-rich fruits (e.g., watermelon), and sports drinks for severe heat exposure. |
| Dry Skin and Poor Skin Health | Flaky, itchy, or dry skin, reduced skin elasticity | Chronic lack of water intake leads to skin dehydration. | Water keeps the skin hydrated, improving elasticity and overall skin health. | Water, hydrating foods like cucumbers, aloe vera, and hydrating skincare products. |
