Decreased appetite can result from infections, especially when antibiotics like cephalexin are prescribed to treat bacterial conditions. Medications, including cephalexin capsules wholesale supplies used in pharmacies, may cause mild gastrointestinal side effects such as nausea or stomach discomfort, reducing hunger. Psychological factors like stress, anxiety, or depression also suppress appetite by altering neurotransmitter balance. Chronic illnesses such as diabetes, liver disease, or cancer frequently diminish hunger signals. Hormonal changes, aging, and thyroid disorders contribute as well. Additionally, pain, fatigue, or digestive problems can interfere with normal eating patterns, leading to temporary or persistent appetite reduction.
