Dehydration

Dehydration occurs when the body loses more fluids than it takes in, disrupting the normal balance of water and electrolytes needed for essential bodily functions. It can range from mild, easily correctable fluid loss to a severe, life-threatening state, particularly in infants, older adults, and those with chronic illness. Common triggers include excessive sweating in hot climates, vomiting, diarrhoea, fever, and inadequate fluid intake, all of which are frequent in India's hot and humid conditions. As fluid losses increase, the body's ability to regulate temperature, circulate blood, and maintain organ function becomes progressively compromised. Prompt recognition and fluid replacement usually reverse mild to moderate dehydration quickly and effectively.

The most common symptoms include: Excessive thirst; dry mouth and lips; dark yellow or reduced urine output; fatigue and weakness. Early recognition is key to prompt diagnosis and effective treatment.

No, Dehydration is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

Treatment options include: Mild to moderate dehydration is treated with oral rehydration solutions that replace both water and essential electrolytes in the correct balance; along with addressing the underlying cause such as vomiting or diarrhoea. Severe dehydration requires hospitalisation for intravenous fluid replacement and close monitoring of electrolyte levels and kidney function. Gradual reintroduction of normal fluids and a light diet is recommended as symptoms improve.. Treatment should always be guided by a qualified General Medicine specialist. Do not self-medicate.

While Dehydration cannot always be fully prevented, several measures can reduce risk: Drinking adequate water throughout the day; increasing fluid intake during hot weather or illness; using oral rehydration solutions during vomiting or diarrhoea.

Consult a General Medicine specialist if symptoms persist for more than a few days, worsen despite home care, or significantly affect your daily activities. Early diagnosis leads to better outcomes.
