Can you gain weight from 100 units of Botox injected into your underarms?

I do not think your weight gain is the result of the Botox injection.  A change in lifestyle, eating habits, sleeping routine, exercise, etc…. are all associated with changes in your weight.  Botox is not.  I guess the so called freshman 15 can be real!  

Hello, Thank you for your question. Weight gain is not an associated side effect of a Botox injection. Take care. 

There is no way that botox can cause weight gain. I suggest you see a cosmetic dermatologist with experience in botox and consider an internal evaluation to ensure there is nothing hormonally going on with you.  Best, Dr. Emer.

Weight gain is NOT a side effect of Botox. The mechanism of action of Botox doesn't have any physiologic (medical reason) connection with  weight gain. Weight gain in the United States is very likely to a combination of a non-healthy diet based on excess of calories, fast food and lack of daily exercise. Botox is an FDA approved treatment that has undergone extensive research. The FDA approved packet insert that contains the list of side effects doesn't list "weigh gain" since it is not a side effect of the product 

The weight gain you have is not from Botox. Botox doesn't affect a person's weight. Botox is great for hyperhidrosis and for correcting wrinkles. Thanks for sharing!

Thank you for your question.  Botox injections typically result in swelling, redness, and possibly bruising, but they do not cause 20 pound weight gains.  I would speak to your injector, as well as your primary care doctor, about the possible causes of the rapid weight gain.  Best wishes!

Thank you for your question regarding recent Botox injection and weight gain.  There is no correlation between receiving Botox injections, under the arms or anywhere else, and weight gain. It is probably related to other factors. I always recommend seeing a board certified plastic surgeon who commonly
performs these procedures for proper advice.

Hi Lauren1596, thank you for your question! Botox is an FDA approved treatment for excessive underarm sweating (axillary hyperhidrosis). Weight gain is not a side effect of Botox. However, stress and diet changes can be common causes of weight fluctuation in students. If you are experiencing rapid weight gain I recommend seeing your primary care physician. 
I've created a video that reviews treating underarm sweating with Botox. I hope this information is helpful in your research!

Thank you for your question lauren1596. Botox is a purified protein used to address wrinkles associated with facial expression. It can also be used in the underarms, palms, and soles for excessive sweating. Weight gain is not a side effect associated with Botox. Stress can cause weight gain as many people eat when stressed. I remember I gained weight when I was a student myself. Please consult with a doctor for specific advice. Good luck!

Botox injections do not directly cause weight gain. If you have gained a significant amount of weight and have not changed your diet or exercise I would advise you to consult your internist to evaluate if there is a hormonal cause.  Best, Dr. Green
