Diarrhoea can lead to dehydration, which may cause a temporary increase in heart rate as the body tries to maintain blood flow. Additionally, electrolyte imbalances from fluid loss can further worsen blood pressure. It is important to stay hydrated and consult a doctor if symptoms persist or become severe.

Call emergency services immediately. While waiting for help, have the person sit or lie down, keep them calm and comfortable, and loosen any tight clothing. If they are not allergic and can swallow, give them a standard dose of aspirin (usually 325 mg) to chew, as it can help reduce blood clotting. If they become unconscious and are not breathing, perform CPR or use an AED, if you are trained, until medical assistance arrives.

High blood pressure and irregular heartbeats can be caused by various factors, including heart disease, electrolyte imbalances, diabetes, thyroid disorders, stress, poor diet, or obesity. Certain medications, caffeine, alcohol, and excessive exercise may also contribute. It is important to consult a doctor for an accurate diagnosis and management plan. Lifestyle changes, such as a balanced diet and regular moderate exercise, can help improve these conditions.

A heart attack, or myocardial infarction, occurs when blood flow to the heart is blocked, often due to a blood clot, causing damage to the heart muscle. Warning signs may include chest pain or pressure, shortness of breath, nausea, or pain radiating to the arm, neck, or jaw. The risk can be reduced by managing blood pressure, cholesterol, and diabetes, avoiding smoking, and maintaining a healthy lifestyle. Consult your doctor if you have any concerns.

Pain in the chest and arm can be symptoms of a heart attack and should be treated as a medical emergency. Contact your doctor or call emergency services immediately. While waiting for help, stay calm, sit or lie down, and avoid any physical activity.

Early warning signs of a heart attack include chest pain, shortness of breath, nausea, sweating, and pain radiating to the arm, neck, or jaw. For a stroke, symptoms may include sudden weakness or numbness on one side of the body, difficulty speaking or understanding speech, vision changes, dizziness, or a severe headache. If you notice any of these symptoms, seek emergency medical help immediately.

Chest pain in someone with high blood pressure and high blood sugar may indicate heart-related complications, such as angina or a heart attack. It may also be caused by less serious conditions, like muscle strain or acid reflux, but cardiac causes must be ruled out urgently. Seek immediate medical attention if the pain is severe, radiates to the arm, neck, or jaw, or is accompanied by sweating, nausea, or shortness of breath.
