Weight loss is widely seen as advantageous to one’s overall health and well-being. When people increase their physical activity while lowering their calorie consumption, they usually lose weight. Some people, on the other hand, lose weight without making any deliberate or conscious effort. Unexpected weight loss is common following life-changing or traumatic events, such as the death of a loved one, divorce, or a job loss. It could also be the outcome of a medical problem. As a result, it’s critical to learn more about the causes and effects of anorexia.
What is the definition of unexplained weight loss?
Unintentional weight loss is described as a loss of body weight that occurs when a person is not attempting to reduce weight by adjusting their food habits or physical activity regimen. Loss of at least 5% of weight over a period of 6 months to a year is considered “unexplained” by physicians.
Unexpected weight loss can have a variety of causes.
Hyperthyroidism:
An overactive thyroid, often known as hyperthyroidism, is a disorder in which the thyroid gland produces more hormones than it should. The thyroid gland produces hormones that aid in the regulation of the body’s metabolism. The production of these hormones in excess speeds up the metabolism, causing the body to burn greater energy and calories than normal. Inadvertent or unexplained weight loss results as a result of this. Graves’ disease, thyroiditis, excessive iodine intake, medication errors, and pregnancy are all circumstances that can induce hyperthyroidism.
Diabetes:
Type 1 and Type 2 diabetes are common types of diabetes. Unexpected weight loss can occur in patients with both forms of diabetes, but it is more common in Type 1 diabetics. Type 1 diabetes is an autoimmune illness in which the immune system attacks insulin-producing cells in the pancreas. The body cannot convert the glucose from food to energy without insulin. High blood glucose levels develop as a result of this. The excess glucose is excreted from the body through urine by the kidneys. Calories leave the body as excess glucose exits. This leads to inadvertent weight reduction over time.
Muscle wasting:
Muscle loss, commonly known as muscle atrophy or muscle wasting, occurs when muscle tissues shrink or waste away. When a muscle is not used over a long period of time, it develops into this disease. People who do not exercise, work at a desk job, or are bedridden are the ones who are most affected. Weight loss that is unexplained can be caused by the loss of comparatively substantial muscular tissue.
Malnutrition, injury-induced inactivity, ageing, burns, strokes, nerve damage, osteoarthritis, rheumatoid, osteoporosis, sclerosis, amyotrophic lateral sclerosis, and other conditions can all cause muscle loss. Nutrition, exercising regularly, and physical treatment can help to prevent or reverse the illness.
Depression:
Depression, often known as clinical depression, is a prevalent mental illness marked by persistent sadness. The disorder has an impact on how a person feels, thinks, and goes about their everyday activities. Constant melancholy, loss of interest in favourite hobbies, low energy, poor focus, muscle discomfort, impatience, sleeping too little or too much, and constant suicidal thoughts are all common signs of depression.
Weight loss that is unexplained might sometimes be a sign of a mental illness. It has the potential to influence appetite and cause changes in eating patterns, resulting in weight loss. According to researchers, patients with depression may have a reduced interplay between the hypothalamus, pituitary gland, and adrenal glands. The functioning of the gastrointestinal or digestive system is thought to be affected by this interaction.
Inflammatory bowel disease is a type of bowel disease with Chronic inflammatory disorders of the gastrointestinal or digestive system. Immune system dysfunction is the most frequent cause of IBD. IBD is divided into two types: Crohn’s disease and ulcerative colitis. While Crohn’s disease can cause inflammation throughout the gastrointestinal system, ulcerative colitis mostly affects the colon and rectum. Fatigue, fever, regular diarrhea, stomach pain, and bloody stools are all common symptoms of IBD.
Weight loss is caused by a disease that impairs the body’s capacity to digest and assimilate nutrients from food. Ghrelin, the hunger hormone, and leptin, the satiety hormone, are both disrupted by IBD, resulting in decreased appetite and weight reduction. Because both types of IBD have no known cure, treatment mainly consists of dietary assistance, medicine, and, in rare situations, surgery.
Cancer:
Cancer is a phrase that refers to a group of disorders in which aberrant and mutant cells develop rapidly and eventually infiltrate healthy tissue. According to the American Cancer Society, one of the first indicators of cancer is unexplained weight loss. Cancers of the blood, lungs, colon, liver, stomach, pancreas, and oesophagus are all known to cause weight loss.
Inflammation in the body is exacerbated by malignant cells. Muscle atrophy is promoted by inflammation, and appetite-regulating hormones are disrupted. The quantity of energy burned by the body when at rest can also be increased by a growing tumor. When the REE level is high, the body burns more calories, resulting in weight reduction.
Rheumatoid arthritis:
Rheumatoid arthritis is a chronic inflammatory autoimmune disease in which the immune system assaults the healthy cells that line the joints. The main symptoms of RA are joint swelling, stiffness, and discomfort. The metabolism is sped up as a result of the chronic inflammation induced by RA. The body is forced to consume more energy and burn more calories as a result of the higher metabolism. As a result, unexplained weight loss occurs. Furthermore, muscle loss caused by RA might exacerbate weight loss in persons who are unable to exercise due to joint discomfort and stiffness.
Addison’s illness, Celiac disease, chronic obstructive pulmonary disease (COPD), TB, endocarditis, and heart failure are all possible causes of unexplained weight loss.
Diagnosis:
If a person has dropped at least 5% of their body weight without exerting any effort over the last 6 to 12 months, they should see a doctor. During the appointment, the physician will most likely inquire about the patient’s medical history. He might also conduct certain physical exams. Tests such as a complete blood count, thyroid panel, sugar levels, urinalysis, renal function, liver function, inflammation, and others will be used in the diagnosing process.
To rule out medical disorders like rheumatoid arthritis, hyperthyroidism, and cancer, imaging procedures like a chest X-ray, computed tomography, and magnetic resonance imaging scan is used. Endoscopic techniques such as upper GI endoscopy or colonoscopy may be recommended to determine whether or not the unexplained weight loss is caused by a gastrointestinal disease.
Treatment and pick-up:
The most common treatment for unexplained weight loss is to identify and treat the underlying medical issue. If the diagnosing process fails to reveal any underlying conditions, the doctor would most likely advise waiting and watching. During that time, he may also recommend that you follow a special diet.
It’s very normal for your body weight to vary from time to time. While losing weight without making a deliberate effort may seem appealing, if a person has lost more than 5% of their body mass in an unexplainable manner, it is critical to uncover the specific cause. Unexpected weight loss can be a sign or symptom of a serious condition like cancer, IBD, or rheumatoid arthritis, among others. As a result, if you lose weight unintentionally, you should see a doctor.
