Dehydration – Causes, Signs, Symptoms & Prevention

Human body comprises 75% water which is present in both intracellularly and extracellularly. Dehydration refers to a condition that involves excessive loss of body water, leading to disturbed metabolic processes. It is generally an imbalance between water loss vs. water intake. CAUSES Diarrhea – Usually when large intestine is unable to hold water in a condition like fever or infections, it excretes water resulting in dehydration. Vomiting – Nausea & vomiting restricts the ability to hold down water thereby reducing the intake. Sweating – In certain conditions like humid and hot weather, strenuous physical activity and fever, the sweating increases. This is body’s defense mechanism which leads to dehydration. Diabetes – Due to the consistent rise in blood sugar, the body tends to excrete glucose via urine, removing water along with it and leads to dehydration. Frequent urination – Conditions like diabetes, excessive alcohol intake, and certain medications such as diuretics, antihypertensives, antihistamines, antipsychotics, leads to frequent urination. Burns – Skin is the first protective barrier for the body which also regulates fluid loss. Dehydration in burn cases is caused due to the inability of the skin to prevent this fluid loss. Signs & Symptoms Mild to moderate dehydration can lead to signs & symptoms like: Increased thirst Dry mouth Tired & sleepy Decreased urine output Yellowish color of the urine Headache Dizziness Dry skin Muscle cramps Palpitations Bad breath Dry eyes & blurred vision Severe dehydration can lead to following symptoms: Results in low urine output along with a change in color to deep yellow. Dizziness may hamper regular walking and standing. Low blood pressure Rapid heart rate...

Heat Stroke – Causes, Symptoms and Precautions

Heat Stroke Heat stroke, sometimes also referred to as Sunstroke is a condition caused by overheating of your body accompanied by dehydration that happens usually as a result of prolonged exposure to or physical exertion in high temperatures. It is a life-threatening condition where the body temperature rises above 104 F or higher. Heat stroke can be fatal and can damage your brain, kidney, heart and muscles. If left unattended it can pose serious complications or death. Symptoms of Heat Stroke A body temperature of more than 104 °F is Hallmark symptom of Heat Stroke. However, some individuals can develop symptoms of heat stroke suddenly and rapidly without warning. Common symptoms include:   Dizziness Nausea and vomiting Hot and dry skin Lack of sweat despite the heat Strong or weak rapid heart beat Shallow breathing Altered mental behavior: Confusion, Disorientation, Irritability, Delirium and Slurring of Speech Seizures and unconsciousness People at Risk Heat Stroke is most likely affects elderly (Age above 50years) and children (Below 4years). The reason behind this is that they adjust to heat slower than young individuals. Apart from them, heat stroke can also affect young athletes, outdoor workers.  However, it can also affect individuals who don’t drink enough water, having a chronic disease or drink an excessive amount of alcohol. Leaving infants, children or animals in cars poses a risk for heat stroke. Even in moderate weather, the temperature inside a closed car can reach dangerous levels. Causes of Heat Stroke Our body normally generates heat as a result of various metabolisms, which is usually dissipated in the form of sweat. In some conditions of extreme...
