About Gastric Cancer Fatigue

Gastric cancer fatigue symptoms are very common and there are a lot of reasons for this. We all suffer tiredness, but this is something different as I am sure you are aware.

Lack of energy can have not only a physical effect, but also a mental one too. Not being able to do the things you want to do - no get up and go - really is very disabling. It’s not only you that it affects, but also the people around you who worry about you too.

What Is Gastric cancer Fatigue?

So what is it? Well, it really is that overwhelming feeling of tiredness, lack of energy, inability to do things both physically and mentally due to the lack of ability to concentrate.

I’m sure you have had it at other times in your life, although not to the same degree? Perhaps you had it during or after being unwell with the flu or other viral illness.

But, this is different because unlike a normal recovery from an illness, these symptoms are persistent. Gastric cancer fatigue can go on for months, even after you have stopped your treatment. It can take up to a year after completing curative treatment for you to start feeling your normal self.

Why? Because there are a lot of different factors involved. So....

What Causes it?

There are many different reasons for your symptoms. These include:

Lack of Sleep

Yes, it’s true. Lack of sleep is common in patients with stomach cancer. This may be because you are worrying about your illness which is perfectly understandable. Your drugs may be causing you to have sleepless nights too. Steroids for example are a commonly used drug and one of their side effects is lack of sleep or insomnia. If you are having problems with pain or discomfort, this can disturb sleep.  All these issues can be helped and your doctor should be able to give advice on this. t may be something as simple as a medication to help you sleep or a change in the drugs you are having. It might just mean a change in the dose of your drugs or a change in the time you take them. For example, steroids should normally be given first thing in the morning rather than later in the day when it is more likely to cause issues with your sleep leading to gastric cancer fatigue.


Worrying is almost universal. You may worry about yourself or those around you, worry about what the doctors are going to tell you at your next appointment or about the treatment you are having. May be you are worrying because of the financial implications of all this. You might have been in employment and now suddenly you are on sick leave or worse still unemployed.

Whatever the cause, you really shouldn't be worrying about these things as you need to concentrate on getting better. 

Certainly your doctor will want to know if your experiencing these feelings  as they will be able to offer help that can reduce gastric cancer fatigue symptoms. This may be in the form of medication or perhaps a form of treatment known as cognitive behavioral therapy where you will be able to talk through your issues.

There are plenty of support organisations who will be able to give you advice such as financial support and care. You can find details of these organisations in the resources section of the website. Never leave things mulling over in your head, let someone know and do talk to those close to you about these feelings.


Anemia or blood loss is common for so many reasons. It can be related to your treatment, the tumor itself or bleeding from your tumor.

Anemia can cause fatigue, breathlessness, muscle aches, headaches, dizziness, chest pains and much more.

Fortunately, this is treatable with tablets, liquids or injections to correct your iron levels, may be EPO or erythropoietin to stimulate blood cell production or even a blood transfusion

Lack of Food

It’s not too surprising that you may be feeling this way because you are not getting adequate amounts of food in.

If this is a concern to you, let your doctor know. There are always options available to help with this.

Lack of Exercise

Lack of exercise often leads to fatigue. The less you do, the less your body wants to do and you feel fatigued.

It’s difficult if you are feeling unwell to think of exercise, but it is important that you try.

Perhaps a short walk, a swim, a trip to the shops or just getting out can make a difference.

Keeping your stamina going is very important, particularly once you have stopped treatment.

Treating Fatigue

I have already to somethings you can try. One very important thing though is making sure your doctor is aware that you are suffering from this.

Going for your therapy can sap your energy, particularly if you have to get there ‘under your own steam’. Usually there are people around who are more than willing to help out with transport, shopping etc.

There is ALWAYS something that can be done to help you.
