For many people, seeing a dramatic decrease on the scale may be something to celebrate. However, in reality, losing weight quickly isn’t always a good thing. It may be a red flag for something much more serious, which is why it’s important to determine the cause. In truth, losing weight due to a healthy diet and exercise is something to be proud of, yet if there’s no apparent reason why you should be losing weight, you might want to see your doctor before you pop open a bottle of champagne. 

Here are some potential causes of sudden weight loss that you might want to consider.


Many people don’t realize just how closely linked our appetite is to our emotions. For some people, this might mean eating more than usual when they’re feeling down, while for others, it may mean not eating at all. 

For people whose appetites dramatically go down during a period of depression, this may be the reason for your sudden weight loss. So, ask yourself whether your mood swings may have something to do with your weight. Remember, neglecting your nutrition is not a long-term solution. Too much or too little food is too much of a shock for your body.


Despite how much we may trust our doctors that the medication they give us is for our well-being, the truth is that sometimes it may have side effects. Certain medications may boost your metabolism and lead to unintentional weight loss. Some antidepressants, and even antibiotics, can cause extreme weight loss, so ask your doctor whether this may be the case.

Digestive Issues

Some conditions such as celiac disease and irritable bowel syndrome can interfere with the way that your stomach absorbs nutrients. As such, you may experience symptoms like diarrhea, meaning once you eat, everything immediately exits your body. In other words, even though you’re eating, the calories and nutrients aren’t making their way into your body. So, even though you may feel full initially, you’re not actually eating since your body is purging right away.

Increased Activity

Perhaps you’ve recently experienced a lifestyle change, and you’re walking or running around more than usual. If so, this may very well be the cause of your weight loss. If you’re burning more calories than you’re consuming, then this will result in a caloric deficit and indeed lead to weight loss. 

This is a great thing— as long as you want it to be. At least you know that your weight loss is due to something healthy and not something more concerning. However, if you want to be sure, you should always consult with your doctor to get their opinion. Unless the advice comes directly from a healthcare professional, then it’s nothing more than speculation.
