Avoid Trigger Foods: Steer clear of foods that can worsen diarrhoea, such as spicy, fatty, or greasy foods, high-fibre foods, and dairy products (especially if you're lactose intolerant).
Practice Good Hygiene: Maintain good hygiene to prevent the spread of infection. To stay healthy, wash your hands frequently, clean and disinfect surfaces regularly, and avoid exchanging personal belongings with others.
Take Anti-Diarrheal Medications: If your doctor advises, anti-diarrheal medications such as loperamide might help manage diarrhoea symptoms. Always follow your doctor's directions.

Managing a low platelet count (thrombocytopenia) caused by medication usage requires a multi-step approach. Here are some steps to help manage the condition:

Your doctor may recommend adjusting or stopping the medication that is causing a low platelet count. This could involve switching to alternative medication or reducing the dosage.
Monitor your platelet count regularly through blood tests to track any changes. This will help the doctor determine the effectiveness of the treatment plan.
If an underlying condition, such as infection or inflammation, contributes to the low platelet count, your doctor will treat it.
In some cases, alternative treatments like platelet transfusions or medications that stimulate platelet production may be necessary.
Avoid risky activities and certain medications; eat a balanced diet with plenty of water to reduce bleeding risk and boost overall health.
If you experience severe bleeding or bruising, seek emergency medical attention immediately.

Managing Vomiting (If it Happens)

What to Do if Vomiting Persists
