During treatment with sematinib, diarrhea, nausea, and fatigue are the most common side effects. Scientific management can significantly improve the quality of life and ensure smooth treatment.

1、 Coping strategies for diarrhea

1. Dietary adjustments

Choose low fiber, digestible foods (such as porridge, bananas, toast, boiled potatoes).

Avoid greasy, spicy, high sugar, and dairy products, and suspend caffeine and alcohol.

Eat small meals frequently to reduce intestinal burden.

2. Fluid replacement and electrolytes

Drink plenty of plain water or oral rehydration salts daily, in small amounts multiple times.

When watery stools appear, avoid sugary drinks to prevent worsening diarrhea.

3. Medications and Records

If diarrhea persists or exceeds 4 times a day, contact a doctor in a timely manner and do not use antidiarrheal drugs on your own.

Record the frequency and characteristics of bowel movements for doctors to adjust their plans.

2、 Methods to relieve nausea

1. Eating techniques

Choose light, room temperature or cooler foods (such as soda crackers, rice soup, steamed eggs).

Avoid dishes with strong odors, overly sweet or oily flavors, and take a 10 minute walk before meals.

2. Meal distribution and odor management

Divide into 5-6 small meals daily to avoid fasting for too long.

Keep the room ventilated, away from kitchen fumes, and smell lemon or mint to relieve discomfort.

3. Drug combination

If nausea affects eating, the doctor can prescribe antiemetic medication and take it as needed.

Avoid lying flat immediately after taking medication and maintain a sitting or semi recumbent position for 30 minutes.

3、 Management suggestions for fatigue

1. Energy conservation

Disperse daily activities, prioritize important tasks, and incorporate brief breaks.

Avoid prolonged bed rest, get up and walk or do light stretching every 1-2 hours.

2. Mild exercise

Choose walking, Tai Chi, or chair exercises 3-5 times a week for 15-20 minutes each time.

Based on not feeling exhausted, reduce strength when fatigue worsens.

3. Sleep and Psychology

Set a fixed bedtime and wake-up time, and take a nap of no more than 30 minutes during the day to avoid affecting nighttime sleep.

Communicate emotions with family, friends, or psychological counselors to alleviate psychological burden.
