Why Does Cancer Cause Weight Loss?

Weight loss can be one of the early signs of cancer, but why does this happen? Studies have shown that when cancer cells form in the body, they are able to take up large amounts of energy from our bodies. This causes an imbalance in the body’s energy stores, leading to weight loss. Furthermore, cancers can also cause inflammation, affecting our appetite and leading to further weight loss.

Cancer can also cause changes in the metabolism, meaning that even if we are eating a lot, our body is unable to convert this food into energy as efficiently as it normally would. This means that we don’t get the same amount of energy from the same amount of food, leading to further weight loss. Another factor is that some cancer treatments can also cause weight loss and other side effects.

Overall, it’s important to remember that while weight loss could be a sign of cancer, this isn’t always the case. Many other factors, such as stress or changes in diet and lifestyle, can also cause weight loss. If you experience sudden or unexplained weight loss, it’s essential to visit your doctor for a full evaluation because it could signify something more serious. Your doctor can suggest the best courses of action and assist in determining the reason behind your weight loss.

What Type Of Cancer Cause Weight Loss:

Weight loss can signify many types of cancer, including but not limited to ovarian, stomach, lung, and pancreatic cancer. Often, weight loss occurs before other symptoms or warning signs become apparent. Here is a full brief of types of cancer that cause weight loss:

Stomach Cancer:

Weight loss due to stomach cancer is a common sign because the cancerous cells consume the nutrients and energy before the body does, resulting in weight loss. Other symptoms associated with stomach cancer include:

  • Unexplained fatigue or weakness
  • Abdominal discomfort or pain
  • Swollen abdomen
  •  Bloating after meals
  • Decreased appetite
  • Indigestion and heartburn

The reason why stomach cancer cause weight loss is because the cancerous cells grow faster than normal and consume more energy and nutrients. This can lead to a decrease in weight due to the body’s inability to get enough nutrients or calories from food.

 It also affects the absorption of nutrients from food as the tumor grows and blocks off parts of the digestive system. If you continually lose weight without trying, you must contact your doctor and get checked out.

Pancreatic Cancer:

Weight Loss

Early pancreatic cancer frequently has no visible symptoms at all. However, when symptoms do occur, unexplained weight loss is often one of the first signs because cancer can cause the body to break down muscle and fat for energy, which leads to a decrease in body weight.

Other possible symptoms of pancreatic cancer include:

  • Jaundice ( Yelloishw eyes and skin)
  • Pain in the abdomen or back
  • Dark urine.
  • Light-colored stools
  • Itchy skin
  • Belly or back pain
  • Nausea and vomiting
  • Gallbladder or liver enlargement
  • Blood clots
  • Diabetes

If pancreatic cancer is suspected, a series of tests may be done to verify the diagnosis. These tests may include imaging scans, blood tests, and tissue biopsies. Treatment options depend on the location and size of cancer, its stage of development, and the patient’s overall health. Common treatments for pancreatic cancer include surgery, radiation therapy, immunotherapy, and targeted therapy.

Lung Cancer:

Weight loss is a common symptom of lung cancer, although not all people with lung cancer will experience it. Weight loss can be especially concerning if no obvious cause exists. In many cases, weight loss in someone with lung cancer occurs because the infected cells have spread to other areas of the affected body and affect how their organs function. Some other main sign includes:

Weight Loss
  • Coughing that gets worse or doesn’t go away
  • Chest pain
  • Shortness of breath
  • Wheezing
  • Feeling tired all the time
  • Coughing up blood

It may also be due to changes in the person’s diet or appetite. For example, if someone with lung cancer has difficulty breathing due to a tumor blocking their airways, they may not have the energy to eat properly. In addition, people with advanced stages of lung cancer might experience nausea and vomiting, which can further contribute to weight loss.

Lung cancer is one of the leading causes of death worldwide, and it’s important to recognize the symptoms that can indicate its presence. Weight loss is just one of many potential signs of lung cancer, so if you also have other symptoms or signs, such as coughing up blood or chest pain, speak to your doctor about whether further testing might be necessary.

Ovarian Cancer:

People who suddenly lose weight without any change in lifestyle may have ovarian cancer. Weight loss may be gradual in the early stages of ovarian cancer and can happen due to other causes, such as dieting or exercise. However, if weight loss is sudden and unexplained, it may be an indication of ovarian cancer; some other signs include:

Weight Loss
  • Abdominal pain
  • Pelvic Pain
  • Bloating of the abdomen
  • Increased abdominal size
  • Loss of appetite
  • Feeling full quickly when eating

It’s essential to note that not everyone with ovarian cancer will experience weight loss. Some people may even gain weight with ovarian cancer. Weight gain or loss is just one possible symptom of ovarian cancer, so it’s important to seek medical advice if you have any other signs or symptoms that concern you.

What Are The Other Common Causes Of Weight Loss:

Anxiety & Depression:

Anxiety and depression can both cause weight loss, although it is often unintentional. When an individual is feeling anxious or depressed, they may not have the energy to eat properly, causing them to lose weight. Additionally, anxiety and depression can lead to changes in appetite, which might further contribute to an unintentional decrease in body weight.

When people feel anxious or depressed, they tend to be more restless and may not get enough quality sleep. This can lead to fatigue and a lack of motivation which then, in turn, affects their appetite. Additionally, people suffering from anxiety and depression may be more likely to seek comfort in unhealthy behaviors like drinking alcohol or using drugs, which can also contribute to weight loss.

Weight Loss

Sometimes, symptoms of anxiety and depression are so severe that the individual may be unable to commit to any kind of treatment plan or daily routine. This can lead to further health complications like weight loss as well as other physical and mental issues. If a person is experiencing unintentional weight loss due to anxiety or depression, it is important to seek a psychologist’s help as soon as possible.

Medication Side Effects:

Certain medications can cause weight loss as a side effect. Many antipsychotic and antidepressant drugs, for example, can lead to appetite changes, resulting in unintentional weight loss. Other medications, such as diuretics and some heartburn remedies, might also contribute to an individual losing weight without meaning to do so.

It is important to check the side effects listed on your medication and speak to your doctor if you experience any concerning symptoms. If you are taking a medication that might be causing unintentional weight loss, it is essential to seek medical advice about alternative drugs or treatments that may be better tolerated.

Taking the wrong medicines to treat an illness’s symptoms can also cause weight loss. Therefore, it is important to get proper medical advice from a qualified doctor before taking any medication because the wrong use of medicines can lead to more serious health complications or, in some cases, even death.

Chronic Diseases:

The major reason for unintentional weight loss can be due to chronic diseases such as cancer, HIV/AIDS, diabetes mellitus, and many more. These diseases can cause malnourishment and a decrease in appetite, leading to an unintentional loss of body weight. People with chronic illnesses tend to have weakened immune systems, which makes them more susceptible to other illnesses that might further complicate their health.

Weight Loss

Some other chronic diseases like kidney failure and chronic liver diseases can also cause weight loss due to malnutrition. People suffering from chronic diseases like HIV/AIDS and diabetes may not be able to fight off infections as easily as healthy people, so they are more prone to getting other illnesses that can result in weight loss.

It is significant to seek medical advice if you experience any sudden or unexpected symptoms of weight loss because the cause could be an underlying chronic illness. Getting the right diagnosis and treatment as soon as possible can help to prevent further health problems from occurring.

Overactive or Underactive Thyroid Gland:

The thyroid gland plays the most important role in our body because it secretes hormones that regulate various metabolic processes. An overactive or underactive thyroid can cause rapid weight loss and should be checked for if a person experiences significant and unexplained weight loss.

Also, the symptoms of an overactive thyroid include hair loss, irregular menstrual cycle, increased heart rate, and sweating. In the case of an underactive thyroid, the common symptoms are dry skin, constipation, and fatigue. People with enlarged or nodular thyroid can also experience weight loss because they are unable to absorb a sufficient amount of necessary minerals, such as iodine.

In most cases, weight loss due to thyroid diseases can be reversed with proper treatment. Thyroid hormone replacement therapy is prescribed when the problem is identified, and this helps in restoring normal metabolic rate, thus leading to healthy body weight. Therefore, it is important to consult a doctor if you have any of the above mentioned symptoms to prevent further health complications.


Tuberculosis, or TB, is a dangerous infectious disease that can cause unintentional weight loss due to a deficiency of appetite and constant fatigue. People with TB may experience other symptoms, such as fever, night sweats, chest pain, and coughing up blood. The TB bacteria can spread through the air, so people with TB need to take the necessary precautions to prevent the spreading of the disease.

Weight Loss

Weight loss due to TB can be managed by taking medication prescribed by a doctor for an extended period of time. It is essential to consult a healthcare professional if any of the symptoms mentioned above are present in order to get a proper diagnosis and treatment plan.

The treatment of TB can be a lengthy process, so it is important to stay patient and dedicated to the treatment. Nutritionary guidance can also help in managing weight loss caused by TB. A balanced diet with enough calories and nutrients will aid in providing strength during the treatment of TB.

Although weight loss due to TB may seem concerning, it is important to remember that it is treatable with the right medical attention. With timely diagnosis and treatment, people can manage weight loss resulting from tuberculosis.

Dental Problems:

Dental problems can also cause weight loss because poor dental health can make it difficult to chew and digest food. This problem can also be caused by certain types of cancer, such as oral, throat, or esophageal. In these cases, tumors may block the digestive tract or even cause sores in the mouth that interfere with eating.

Dental problems could not be the main cause but can be a contributing factor to weight loss. It’s important to visit your dentist from time to time, especially if you experience any symptoms of dental problems like swollen gums, infections, or sores in the mouth.

Tips and Tricks For Putting on Weight:

Eat Healthily:

When you are trying to gain weight, it is especially important to eat a balanced and nutritious diet. Choose nutrient-dense foods like lean proteins, fruits, vegetables, whole grains, nuts, and seeds. Eating several small meals throughout the day can also help you maintain your energy levels and support healthy weight gain.

Weight Loss

If you have lost weight due to cancer or any other medical reason, then you need to be extra careful about what you eat. You can consume high-calorie liquids and shakes to get the calories you need. Some types of cancer, like stomach or esophageal cancer, can make it difficult to consume solid food. You can ask your doctor for advice on high-calorie liquid supplements or nutritional drinks in this situation.

Stay Active:

It might seem counterintuitive, but physical activity is important for maintaining a healthy weight. Exercise helps boost your metabolism so that you burn more calories. It can also help improve circulation and increase your appetite. Pick an activity you enjoy, like walking, swimming, or biking, and make it a regular routine.

Staying active can also prevent the tissue loss that sometimes happens with cancer treatments. In order to put weight faster, you can also include strength training in your routine because this can help increase your muscle mass. People who keep their bodies active will have a better outcome when gaining weight.

Manage Stress:

Stress can significantly impact your appetite, making it difficult to consume enough calories. Taking steps to manage your stress levels is essential for healthy weight gain. Meditation, yoga, and spending time in nature can all be helpful in reducing stress.

People with anxiety & depression are more prone to weight loss because of low appetite. Concentrating on positive activities like reading, gardening, or playing a musical instrument can help in reducing stress and anxiety. In order to manage mental health issues, it is also helpful to speak to a therapist.

Weight Loss

If you want to put on weight, then you need to stay positive because mental health is an important aspect of physical health because it plays a role in maintaining your weight. Doing little things that make you happy can help you stay focused and motivated to reach your goal.

Monitor Your Progress:

It might be challenging to perceive your development when you look in the mirror every day. So, monitor your development. Record your weight at the start and every week. In this manner, you’ll have something to look back on and be able to gauge your development.

Taking images of oneself at the start and during the procedure is also a wonderful idea. You get the chance to observe the outcomes because of this, truly. You can also schedule body measurements with a professional if you want to track your body fat percentage.

Whether you keep track of your progress yourself or hire a professional, this will give you a better idea if unexpected weight loss is the result of cancer or something else so you can take proper precautions or treatment.


Weight loss can be a sign or symptom of cancer, but it is not always the case. There are many other reasons for weight loss, such as diet and exercise changes, that do not necessarily mean cancer is present. You should pursue medical attention if you experience substantial weight loss without apparent reasons. This might be a sign of cancer.

There are many different types of cancers, so it is essential to get a precise diagnosis from a medical professional. Earlier detection of cancer increases the chance of successful treatment. It is also important to maintain your health & fitness so that you have the best chance of fighting any potential illnesses.
