You can become sick for a variety of causes, including any bacterial or viral infection or any medical problem. When you are sick, it's a typical observation that you drop a few pounds, but the cause of this is never entirely understood. People speculate that it might be caused by illness, but what actually transpires during illness that results in weight loss? Here, we will discuss why you lose weight when you become sick. Why Do You Lose Weight When Sick? When you're sick, your body goes through various changes that include appetite loss, nausea, a feeling of coldness, shivering, and even weight loss. Let's examine the reasons why you lose weight while you are sick. You lose weight when you are sick due to: 1: Loss Of Appetite The first sign you face when you are sick is that you lose your appetite because your stomach feels that it can not handle much food in it and even thinking of having something to eat makes you nauseous. This loss of appetite will make you eat very little food which will automatically result in a drop in body fat because the body will use the stored fat to provide energy and fight the infection. 2: You Become Calorie Deficit When you become sick, you don’t feel like eating and whatever you eat is lost from the body through vomiting or diarrhea. When you are not eating enough food it means you are taking fewer calories than your body’s requirement, and the calories you eat are also lost from the body which makes you in a calorie deficit state. 3: Diarrhea And Vomiting When you are sick, you mostly feel nauseous and get vomiting and diarrhea which causes a lot of fluid loss from your body. In this condition, it is always challenging to maintain fluid and food in your body because whatever you eat or drink just gets out of the body through vomiting or diarrhea. This fluid loss from the body changes fluid volume and makes you lose some pounds temporarily. 4: Loss of Water Weight Due To Dehydration The weight that is lost due to sickness is not the actual fat but the water weight due to the loss of liquids and fluids from the body that causes fluid imbalance. When you are ill, you have more urine leading to dehydration. The fever you get when you are sick makes the body produce more sweat to cool down the temperature which also causes fluid loss from the body and causes dehydration. Moreover, water is also lost in vomiting and diarrhea all of which result in loss of water weight. 5: Loss of Energy Due To Fatigue When you are sick, your body and muscles are under fatigue as they are fighting off the infection by producing antibodies. In this way, there is no or very little energy left for the burning of calories, so the body uses the stored fat, which results in a drop in weight. The loss of energy also makes you eat less because there is not enough energy left for the digestion of food. How Much Weight Do You Lose When Sick? The intensity and length of your sickness or illness will determine how much weight you will lose. You will only lose a few pounds if you have a moderate illness like the seasonal flu or a cough, but if you have a severe sickness like a viral or bacterial infection, you may lose a few more. Additionally, your present body weight and the indications and symptoms of your sickness must be taken into consideration. For instance, if you experience more vomiting or diarrhea or are unable to eat, you will lose more weight. Conclusion When you are sick due to any reason, you lose weight because of changes occurring in your body that cause loss of appetite, make your calories deficient, cause loss of fluid due to vomiting and diarrhea, loss of water weight, dehydration, and loss of energy due to fatigue. All these factors contribute equally to making you lose weight in sickness.
