This can be a sign of heart disease. Know symptoms and prevention tips

Fainting can be the sign of heart disease. Therefore, one must seek timely medical intervention upon early detection of warning signs to prevent and manage heart-related fainting risks.

Fainting or syncope can be caused due to certain conditions:

1. Dehydration: Dehydration due to excessive heat and sweating-related fluid loss, can cause nausea, dizziness and light-headedness fainting symptoms.

2. Overstimulated nervous system: Identifiable causes like prolonged standing, abruptly standing after lying down, or psychological distress may overstimulate the nervous system or vagus nerve that links the brain to the stomach. Therefore, one may experience initial light-headedness sensations and loss of consciousness at times.

3. Pre-existing medical conditions: Fainting is also a symptom of other pre-existing medical conditions such as hypoglycaemia or low blood sugar among diabetics or hypertension. Certain medications such as psychiatric, diuretics, antihistamines, or heart disease medications can also trigger fainting.

4. Cardiac Syncope: Serious causes include heart-related diseases which can increase cardiac-related death risks. Commonly, cardiovascular causes include irregular heartbeat or palpitations, such as too low heartbeat in bradycardia or too fast heartbeat or tachycardia.

Prevention Tips

Initial fainting symptoms include light-headedness, sweating, nausea, and blurred vision before a blackout or loss of consciousness occurs. However, untreated symptoms can trigger fatal injuries or even sudden cardiac arrests in severe cases. It has become important to take preventive and management measures include:

1. Posture: Commonly, lying down or sitting can deescalate dizziness, sweaty palms and nausea symptoms.

2. Lifestyle: One can prevent heart-related syncope through regular 30 minutes of cardiovascular exercises and eating a diet with nuts, leafy green vegetables, low salt that improve heart and overall health. Particularly, as lifestyle-related disorders and obesity amongst the younger population has widened cardiovascular risks across age groups.

3. Periodic check-ups: Timely intervention and regular check-ups are necessary preventive and management measures for the often trivialized condition.

4. Manage pre-existing conditions: Those with pre-existing heart, diabetes or metabolic diseases must manage their condition through relevant doctor advice and medications.
