Aspirin and Appetite Loss: What You Should Know

Yes, aspirin can be associated with decreased appetite, although this side effect isn’t the most common. Some official patient-facing resources list “loss of appetite” among potential adverse effects of aspirin. ^[1] In addition, aspirin frequently causes stomach-related symptoms like indigestion, stomach discomfort, and nausea, which can indirectly reduce appetite. ^{[2] [3]}

How Aspirin Might Lower Appetite

• Gastrointestinal irritation: Aspirin can irritate the stomach lining, leading to symptoms such as heartburn, indigestion, stomach cramps, and nausea, which often suppress appetite. ^{[2] [4] [3]}
• More serious stomach effects: In some cases, aspirin can contribute to gastric bleeding or black, tarry stools; these are urgent warning signs and can coincide with poor appetite. ^{[3] [5]}
• Systemic side effects: General tiredness or weakness may accompany aspirin use and can reduce interest in eating. ^[1]

While decreased appetite can occur, any persistent appetite loss should be discussed with a clinician to rule out stomach irritation or bleeding. ^{[3] [5]}

When to Seek Medical Help

• Urgent symptoms: Vomiting blood, coffee-ground vomit, black or tarry stools, faintness, or stomach pain that does not improve are signs of possible bleeding and need prompt medical attention. ^{[5] [6]}
• Ongoing appetite loss with abdominal pain: If decreased appetite persists and is accompanied by stomach pain, cramping, or burning, check in with a clinician. ^[3]
• Hearing changes with aspirin: Ringing in the ears or hearing loss can signal high salicylate exposure; seek advice if these develop. ^{[5] [6]}

If serious symptoms occur while taking aspirin, it’s safer to stop and get medical advice promptly. ^{[5] [6]}

Practical Coping Strategies

If your appetite is down but there are no red flags, these supportive steps can help you maintain nutrition:

• Smaller, more frequent meals: Eating several small meals or snacks can be easier than three large meals when appetite is low. ^[7]
• Calorie- and protein-dense choices: Opt for shakes, smoothies, yogurt, nut butters, eggs, beans, and dairy to pack more nutrition into smaller portions. ^{[8] [9]}
• Cold or room‑temperature foods: Cooler foods may be more tolerable if smells trigger nausea. ^[8]
• Pleasant mealtime environment: Soft music, appealing plating, and favorite foods can gently stimulate appetite. ^[10]
• Sip wisely: Avoid large volumes of liquids with meals to prevent early fullness; drink more between meals. ^[11]
• Scheduled eating: Use timers or reminders to keep a steady intake even when hunger cues are muted. ^[11]

If appetite remains poor, ask your clinician about medications or adjustments to your pain regimen that might help. ^[12]

Medication Tips and Alternatives

• Take aspirin with food: This may reduce stomach irritation and related nausea, helping appetite. ^[2]
• Dose review: Discuss whether your dose, formulation (enteric‑coated), or timing can be adjusted to ease stomach side effects. ^[5]
• Consider alternatives: Depending on your condition, a clinician might suggest a different pain reliever or add a stomach-protective option when appropriate. ^[5]

Never change or stop aspirin prescribed for heart or stroke prevention without medical guidance. ^[5]

Bottom Line

Aspirin can sometimes cause loss of appetite and commonly triggers stomach symptoms that suppress eating; persistent appetite loss or any signs of bleeding should be evaluated promptly. ^{[1] [2] [3] [5]} With supportive nutrition strategies and careful medication use, most people can cope safely and maintain adequate intake while addressing underlying causes. ^{[10] [8] [9] [11] [12]}
