Afatinib may cause side effects such as nausea, diarrhea, and fatigue during treatment. Through scientific lifestyle adjustments and proactive communication, most symptoms can be effectively controlled, thereby maintaining continuity of treatment.

1、 Dealing with nausea

1. Dietary adjustments

Choose light and digestible food, such as porridge, noodles, soda biscuits, and avoid greasy, spicy or too sweet food.

Eat small meals frequently and avoid fasting or overeating.

2. Environment and odor

Keep away from kitchen fumes, perfume and other pungent smells.

Maintain indoor air circulation and take a moderate walk after eating to aid digestion.

3. Timely communication

If nausea persists or affects eating, consult a doctor for antiemetic medication.

2、 Dealing with diarrhea

1. Dietary management

Avoid high fiber, raw and cold foods, and dairy products (unless tolerated), and choose low residue foods such as white rice, ripe bananas, and apple sauce.

Pay attention to drinking small amounts of water multiple times, replenish electrolytes, and drink oral rehydration salts in moderation.

2. Skin care

After each bowel movement, gently clean the perianal area with warm water and apply protective cream to prevent skin damage.

3. Seek medical attention promptly

If diarrhea occurs more than 6 times within 24 hours, or if symptoms such as bloody stools, dehydration, dizziness, etc. appear, you should immediately contact a doctor.

3、 Dealing with fatigue

1. Reasonably plan energy

Arrange important activities during the most energetic period (such as in the morning) and take a brief break during lunchtime.

Reduce the intensity of work or household chores appropriately and accept help from family or friends.

2. Gentle activities

Daily short walks or gentle stretching can help improve circulation and mood, but avoid excessive consumption.

3. Sleep management

Maintain a regular daily routine and avoid excessive rest during the day (no more than 30 minutes) to avoid affecting nighttime sleep.

4. Proactive feedback

If fatigue seriously affects self-care ability or causes low mood, it is necessary to inform the doctor in a timely manner and evaluate whether adjustment of the plan is needed.

Important reminder: In case of any serious or persistent discomfort, do not stop or reduce medication on your own. It is necessary to communicate with the medical team and jointly develop an individualized management plan.
