Q. Why do some antibiotics cause a loss of appetite?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Antibiotics are a widely used class of medications that can help treat and prevent bacterial infections. While they can be incredibly effective at fighting off harmful bacteria, they may also have some negative side effects, one of which is a decrease in appetite.
When taking antibiotics, it's not uncommon to experience decreased appetite due to the way antibiotics interact with different parts of the digestive system. One possible cause is an effect on the gastrointestinal (GI) tract which disrupts normal digestion. By reducing or blocking absorption of certain nutrients from food, as well as altering gut microbial populations and GI motility—the rate at which food passes through the stomach—antibiotics may lead to changes in hunger signals from the GI tract and therefore a loss of appetite.
Another potential reason for reduced appetite while on antibiotics is their affect on taste buds and smell receptors in our mouths and noses that work together when we eat food; these senses tell us how much pleasure or reward we get out of eating. When someone takes an antibiotic drug like doxycycline or amoxicillin, it can alter our sense of taste making foods seem less appetizing leading to lower intake even when feeling hungry.
Lastly, some people might also feel nauseous while taking antibiotics which can make them lose their appetite entirely until symptoms pass away after stopping treatment or adjusting doses. On top of this, many types of antibiotic drugs tend to be more sedating than others so feeling drowsy even when you’re not sleeping could reduce your desire for food too since energy levels are low throughout day time hours instead being peaking during meals times like breakfast lunch and dinner when usually being most hungry naturally.
Regardless of why you’re experiencing a reduction in appearence whilst antibiotic use , its important that you try get adequate nutrition through healthy snacks such as fruits veggies nuts whole grains lean proteins etc . Nutritionists recommend increasing intake nutrient-rich high-calorie drinks smoothies soups yogurt etc . if needed just ensure speaking with your doctor first before introducing any new diet modifications supplements vitamins minerals into regular routine .
