When a doctor prescribes antibiotics, a patient is mostly thinking about getting rid of an infection. But quite a few people also observe their appetite or weight to be changing along with the therapy. As a result, they ask whether antibiotic treatment can be related to weight loss or whether some other factor causes these changes?
Apart from antibiotics being the evil-killers of bacteria, they might also affect your body in a way which results in different, albeit temporary, changes in your body weight.
By any measure, antibiotics do not help the "fat burning" process. Still, through various indirect effects, they may eventually bring about a smaller scale figure:
The gut contains thousands of bacteria that influence weight regulation. The so-called "good" bacteria in the gut may diminish due to antibiotics, and the body's nutrient absorption may be interrupted because of that.
Weight Loss vs. Weight Gain: It Depends on the Type
The interesting point that comes through the studies is that an individual's reaction to a drug (type of medication) mainly determines the outcome. Some will shrink their body size due to the combined effects of disease and nausea, while the prolonged or frequent administration of certain antibiotics in some people has been linked to gaining weight as far as later life is concerned because of a permanent change in gut flora.

Well, can antibiotics cause weight loss? Certainly. Yet, this phenomenon is typically associated with loss of appetite resulting from malaise or water weight rather than being a healthy and/or permanent change. So, whenever you notice such a remarkable decrease in weight during a medication course, consulting your doctor is the most advisable thing to do.
One way to safeguard the metabolic functions caused by the medicine would be to get a probiotic that keeps the "good" bacteria in your digestive system replenished.
