It might be caused by a stressful event like a divorce, losing a job, or the death of a loved one. It can also be caused by malnutrition, a health condition or a combination of things.
Unexplained weight loss is a noticeable drop in body weight that occurs even if the person is not trying to lose weight. Unexplained weight loss can be a symptom of a serious illness, including cancer or diabetes. Treatment involves identifying the underlying cause of the weight loss.
If you're losing weight without trying and you're concerned about it, consult your health care provider. As a rule of thumb, losing more than 5% of your weight over 6 to 12 months may indicate a problem.
Hyperthyroidism, or overactive thyroid, develops when your thyroid gland makes too much thyroid hormone. These hormones control many functions in the body, including metabolism. If your thyroid is overactive, you'll quickly burn calories even if you have a good appetite. The result can be unintentional weight loss.
According to the American Cancer Society, significant weight loss happens most often with cancers that affect the stomach, pancreas, esophagus and lung.
But many health care providers agree that a medical evaluation is called for if you lose more than 5% of your weight in 6 to 12 months, especially if you're an older adult. For example, a 5% weight loss in someone who is 160 pounds (72 kilograms) is 8 pounds (3.6 kilograms).
Unexplained weight loss is a decrease in body weight, when you did not try to lose the weight on your own. Many people gain and lose weight. Unintentional weight loss is loss of 10 pounds (4.5 kilograms) or 5% of your normal body weight over 6 to 12 months or less without knowing the reason.
Increase your calorie intake.
One way you can stop losing weight is to increase the amount of calories you eat each day. You should consume at least 1200 calories each day. Try tracking your calorie intake each day using a calorie tracker app, and then add a couple hundred calories each day.
Your body weight can regularly fluctuate. But the persistent, unintentional loss of more than 5 per cent of your weight over 6 to 12 months is usually a cause for concern. Losing this much weight can be a sign of malnutrition. This is when a person's diet doesn't contain the right amount of nutrients.
Your blood pressure can drop if you also lose weight too quickly, which can be dangerous. Dehydration and electrolyte imbalance can also occur. Other side effects of quick weight loss include dizziness, constipation, hair loss, headaches, irritability, fatigue, and muscle loss.
So what is the magic number to lose weight and keep it off? According to the Centers for Disease Control and Prevention (CDC) , it's 1 to 2 pounds per week. That means, on average, that aiming for 4 to 8 pounds of weight loss per month is a healthy goal.
Summary. Weight loss is not a symptom of all types of cancer. It can be caused for a variety of reasons. Sometimes weight loss is directly related to cancer, but other factors such as emotional distress and side effects of treatment can contribute to weight loss.
Involuntary weight loss generally develops over weeks or months. It can be a sign of a significant physical or mental disorder and is associated with an increased risk for mortality. The causative disorder may be obvious (eg, chronic diarrhea due to a malabsorption syndrome.
The majority of cancer patients lose weight at some point in the course of the disease. Weight is sometimes the sign that leads someone to get diagnosed with cancer, but it may occur at any time, such as during treatment or in the advanced stages. Your eating habits may change.
Try smoothies and shakes.
Avoid beverages with few nutrients or calories, such as diet soda. But a blend of high-calorie, nutritious ingredients in a smoothie or shake can help if you're eating on the go. Meal replacement drinks also may be part of your weight-gain effort.
Dried fruits, such as dates, prunes, apricots, figs, sultanas, currants, and raisins, contain more calories than their fresh counterparts, making them great options for healthy weight gain.
Several types of supplements — protein powders, mass gainers, creatine, and pre-workouts — can help you gain weight if you use them in combination with a balanced diet. In general, protein powders and mass gainers are your best bets if you're simply looking to boost your calorie intake.
Weight gain supplements are commonly available over the counter at drugstores. They typically come in the form of pills or powders and claim to boost appetite, metabolism, muscle mass, and athletic performance.
People who need to gain weight can often do this by increasing their intake of foods rich in whole carbohydrates, healthy fats, and protein. Examples include whole grains, dried fruit, potatoes, avocados, oily fish, eggs, and dairy products. A doctor may recommend that people with a low body weight try to gain weight.
According to many experts, losing 1–2 pounds (0.45–0.9 kg) per week is a healthy and safe rate (1, 2, 3 ). Losing more than that is considered too fast and could put you at risk of many health problems, including muscle loss, gallstones, nutritional deficiencies and a drop in metabolism ( 4 , 6 , 7 , 8 ).
