Don't Ignore Unexplained Weight Loss: It Could Indicate A Serious Problem

Weight loss that isn't explained and exhaustion are two of the most typical indicators of a progressing illness.

Do you want to lose weight but can't seem to get rid of it? While it would be so much easier if weight reduction were a piece of cake and you didn't have to put in any effort to lose weight. Doesn't it seem impossible? However, for some people, this is true. Some people lose a lot of weight without dieting or exercising despite doing nothing. It may appear to be good news for someone who is attempting to reduce weight, but it isn't. Weight loss that isn't explained and exhaustion are two of the most typical indicators of a progressing illness. There are a variety of reasons for sudden weight loss, and some of them are listed here.

Common Causes Of Unexplained Weight Loss

Here are 10 common conditions that cause unexplained weight loss.

  • Diabetes

Diabetes is a metabolic illness in which you have excessive blood glucose levels (blood sugar) because your body does not create enough insulin, or your body does not respond to insulin adequately, or both.

Symptoms of diabetes: Frequent urination, excessive thirst, intense hunger, weight gain (type-2 diabetes), significant and sudden weight loss (especially in type-1 diabetes), fatigue, cuts and bruises not healing properly, numbness or tingling in feet and hands.

  • Depression

Depression is a mood condition characterized by feelings of sadness, loss, anger, or frustration that last for weeks or longer.

Symptoms of depression: Not sleeping or sleeping too much, difficulty concentrating, negative thoughts, feelings of hopelessness and /or helplessness, irritability, suicide, and sudden weight loss.

  • Overactive thyroid

The thyroid gland generates thyroid hormones, which govern your body's metabolism, including heart rate, calorie burn rate, and digestion. Calcitonin, a hormone produced by the thyroid gland, regulates the amount of calcium in your blood. Hyperthyroidism occurs when the thyroid gland generates too much thyroid hormone (is overactive).

Symptoms of an overactive thyroid: Palpitations, fast and irregular heartbeat, hot flashes and increased sweating, sudden weight loss, shortness of breath, panic attacks, gritty and bulging eyes, fatigue, mood swings, infertility or decreased libido. However, not everyone has all these symptoms. You may relate to just a few of them. You may relate to many of them, too.

  • Tuberculosis

The bacteria Mycobacterium tuberculosis causes tuberculosis, a dangerous infectious disease. It is primarily a pulmonary disease. Tuberculosis can affect the kidneys, spine, and brain, among other organs. A six-month course of antibiotics can be used to treat the condition.

Symptoms of tuberculosis: Coughing, sometimes with sputum or blood, chest pains, fatigue, unexplained weight loss, fever and night sweats.

  • Chronic obstructive pulmonary disease (COPD)

Chronic obstructive pulmonary disease (COPD) is a collection of lung illnesses that restrict airflow and make it difficult to breathe. Chronic bronchitis is an inflammation of the lining of the bronchial tubes that convey air to and from the lungs that can impede airflow. Emphysema is a condition in which the air sacs in the lungs gradually degrade, making breathing difficult.

Symptoms of chronic obstructive pulmonary disease: Symptoms often don t appear until significant lung damage has occurred. The symptoms are mainly wheezing, shortness of breath, chest tightness, frequent respiratory infections, lips or fingernail beds becoming blue, tiredness and unexplained weight loss in the later stages.

  • Crohn s disease

Crohn's disease is an inflammatory bowel illness that affects the intestines (IBD). It causes inflammation of the digestive tract lining, resulting in stomach discomfort, severe diarrhoea, and even malnutrition.

Symptoms of Crohn's disease: Diarrhoea, abdominal pain, cramps, reduced appetite and weight loss, fatigue, blood in the stool and ulcers.

  • Addison's disease

Addison s disease is a hormonal disorder in which the adrenal glands produce insufficient amounts of hormones, cortisol and, in some cases, aldosterone. It can affect all age groups and both genders.

Symptoms of Addison's disease: Weight loss, fatigue, low blood pressure and muscle weakness.

  • Cancer

Cancer is defined as the uncontrollable proliferation of abnormal cells in any part of the body. Cancer can start in the skin or tissues that line or cover internal organs (carcinoma), in bone, cartilage, fat, muscle, blood vessels, or other connective or supporting tissue (sarcoma), in blood-forming tissue like the bone marrow (leukaemia), or in immune cells (immunoblastoma) (lymphoma and myeloma). The term "central nervous system cancer" refers to cancer that starts in the brain and spinal cord. Metastatic cancer occurs when cancer cells break away from their initial cells and target other organs or tissues. Are you aware of these eight cancer causes that you encounter on a daily basis?

Symptoms of cancer: Signs and symptoms vary according to the type of cancer. Some of the common symptoms are sudden weight loss, fatigue, unexplained muscle or joint pain, night sweats, lump or thickening under the skin (for example, breast cancer), changes in bowel or bladder habits (bowel cancer), skin changes or changes in the size and colour of moles (skin cancer), hoarseness and difficulty swallowing (lung cancer).


The Human Immunodeficiency Virus (HIV) is similar to other viruses, with the exception that whereas the human immune system can remove other viruses, it cannot eradicate HIV. HIV, on the other hand, disables the immune system, making it impossible for your body to fight infections and diseases, and AIDS is the last stage of HIV infection.

Symptoms of HIV/AIDS: HIV infection as such may or may not show symptoms of fever, rash, sore throat, muscle aches, swollen lymph nodes, ulcer in the mouth and fatigue, but when the HIV infection progresses to AIDS, all these symptoms are prominent. In addition, there is sudden weight loss due to wasting, cough and shortness of breath, chronic diarrhoea and blurred and distorted vision.

  • Parkinson's disease

Parkinson s disease is a progressive disorder of the nervous system that causes stiffness in the body and face or slowing of movement. This disease cannot be cured but medication can improve the symptoms. Read more about yoga to help you live with Parkinson's disease.

Symptoms of Parkinson's disease: Impaired posture and balance, loss of automatic motions such as blinking, laughing, or swinging arms while walking, rigid muscles, changes in speech and writing, and abrupt weight loss are some of the symptoms. However, as stated by Dr. Melissa Nirenberg, weight loss is NOT one of the key signs of this disease. People with PD frequently lose weight before receiving a diagnosis for a variety of reasons, including a loss of smell and taste. Once they are on the right Parkinson's medication, they usually stop losing weight. As a result, chronic, unexplained weight loss in people with Parkinson's disease should never be attributed to the disease until more serious medical concerns like cancer and depression have been ruled out.
