I'm sorry to hear you're experiencing these symptoms. Diarrhea, high heart rate, high blood pressure, and blood sugar issues together can be concerning and may indicate an underlying health problem that needs prompt attention.

Here are some important steps you can take:

• Seek immediate medical evaluation: These symptoms require assessment by a doctor, preferably a cardiologist or an endocrinologist, to determine the cause and appropriate treatment.
• Monitor your vital signs: Keep track of your blood pressure, heart rate, and blood sugar levels if you have the means to do so.
• Stay hydrated: Diarrhea can cause dehydration, which may worsen your symptoms. Drink plenty of fluids like water, oral rehydration solutions, or clear soups.
• Avoid self-medicating: Do not start or stop any medications without consulting your doctor, especially if you are on blood pressure or diabetes medications.
• Lifestyle considerations: Once stabilized, managing blood pressure and blood sugar often involves a balanced diet rich in millets, dals, vegetables, and controlled salt and sugar intake, along with regular physical activity.

Given the complexity and potential seriousness of your symptoms, please contact a specialist doctor urgently or visit the nearest emergency facility. If you experience severe chest pain, difficulty breathing, confusion, or fainting, call emergency services immediately.
