Lifestyle changes may not directly affect the cancer itself but it can help to:

  • Strengthen your body to better manage side effects of treatment.
  • Make your immune system stronger to help in the fight against cancer.
  • Improve your emotional outlook and overall wellness.
  • Lower the risk of other medical problems that could affect your health.

There are also steps you can take to help direct your care and make sure your team and family know your wishes. This information can provide comfort and decrease stress in difficult times.

Quit Smoking

Smoking may make stomach cancer treatment less effective and increase the risk of complications. Smoking slows tissue healing and can cause irritation to the esophagus and stomach, which may already be very irritated from treatments.

When you quit smoking , the body immediately begins to repair itself. Quitting will help boost your immune system to help fight the cancer and improve recovery from treatment. It will also reduce your risk of future cancers.

Nutritional Support

A good diet can affect your overall health, energy, mood, and ability to recover. Unfortunately, treatment of the cancer itself may decrease your appetite or make it difficult to eat. Consult with a registered dietitian (RD) about meal planning. Meal planning is an important step in helping you get the most nutrition out of your foods, and stop or slow unintended weight loss.

A feeding tube may be needed to help deliver nutrition after surgery or if you have problems eating. It allows nutritional mixes to be delivered directly to the small intestine.

Reduce Your Risk of Infection

Cancer and its treatments suppress the body's immune system. This can increase the risk of infection, or increase the severity of common infections, like a cold or the flu . To decrease the risk of infection while going through cancer treatment:

  • Wash hands thoroughly and often. Hand washing is the most effective method of decreasing the chance of catching colds and flu. Carry hand sanitizer for times when washing is not convenient.
  • Try to avoid crowds, especially during cold and flu season.
  • Avoid touching eyes, mouth, and nose to after coming in contact with surfaces or objects.
  • Clean and disinfect surfaces and objects often.
  • Ask your doctor about immunization against the flu and pneumonia .

Exercise Regularly

If you have not been exercising regularly, check with your doctor to choose safe exercises. Exercise has many benefits that may help you withstand the physical and emotional stresses of cancer and cancer treatment including:

  • Promoting overall fitness
  • Boosting your energy level
  • Improving your immune system
  • Boosting your spirits and improving your emotional outlook

It is important to balance rest and activities to prevent becoming too tired. Consider talking to a trainer who can help with designing an exercise program.

Manage Fatigue

Fatigue is the most frequently experienced symptom of cancer and cancer treatments. This is especially true with stomach cancer. To help avoid getting overtired, prioritize tasks and focus on the most important ones. It is important to allow others to help you with daily chores, shopping, and preparing meals. If needed, plan time throughout the day for rest.

Fatigue will also be more pronounced without proper nutrition. Talk to your doctor if fatigue is affecting quality of life.

Seek Support

The diagnosis of cancer is a life-defining event that can be difficult to handle. Facing the uncertainty of a serious disease, feeling anxious about treatment, lifestyle changes, and worrying about the impact of cancer can be overwhelming. It is important to rely on family, friends, and other people in your life. People who allow themselves to seek help while they are recovering from cancer can often maintain better emotional balance. Other sources of support include:

  • Religious community
  • Support groups for people with your type of cancer
  • Professional support from social workers, psychologists, and/or psychiatrists who are trained to help support cancer patients and their families

Family and caregivers may also need support. Encourage them to seek support groups or counseling geared toward them.

Comfort Measures

Stomach cancer is especially difficult because it is usually found in advanced stages, making it harder to treat. Some people choose treatments to ease cancer complications or choose to stop treatment completely. Depending on your circumstances, it may be realistic to begin end-of-life planning. Considerations may include:

  • Choosing home or hospice care
  • Financial decisions
  • Advance directives—includes legal issues, like wills, hospital orders for your care, and power of attorney for medical care and finances
  • Insurance coverage

If you need guidance, talk to a member of your healthcare team. You can be referred to a trained professional to guide you through the process.
