Decreased appetite can occur for many reasons, ranging from temporary conditions to underlying health issues. Common causes include stress, anxiety, and depression, which can suppress hunger signals. Acute illnesses such as infections, fever, or gastrointestinal upset often reduce appetite as the body prioritizes recovery. Medications, including antibiotics or pain relievers, may also alter taste or cause nausea; this is sometimes noted when discussing products like cephalexin capsules wholesale in pharmaceutical contexts. Hormonal changes, aging, sleep deprivation, and chronic diseases such as diabetes or thyroid disorders can further contribute. Identifying the cause is important for appropriate management.
