Can atorvastatin 20 mg cause loss of appetite?
Yes. Loss of appetite (reduced appetite) is a possible side effect of atorvastatin, including at 20 mg. People taking statins can report stomach-related effects such as nausea, indigestion, or abdominal discomfort, which can lower appetite.
What other stomach symptoms might come with it?
If appetite loss is related to atorvastatin, it may occur alongside other gastrointestinal (GI) symptoms, such as:
- Nausea or upset stomach
- Heartburn/indigestion
- Abdominal pain or discomfort
- Diarrhea or constipation
These kinds of effects are commonly what patients mean when they say their “appetite is off” on a statin.
When should appetite loss be treated as urgent?
Seek urgent medical care if reduced appetite comes with signs that could point to a serious reaction or liver/muscle problems, such as:
- Yellowing of the skin or eyes (jaundice)
- Dark urine or severe fatigue
- Severe or persistent upper-right abdominal pain
- Severe muscle pain, weakness, or fever
- Rash, facial swelling, or trouble breathing
What should you do if appetite loss starts after starting atorvastatin?
Contact the prescriber promptly to discuss whether to:
- Check for other causes (new illness, diet changes, other medications)
- Temporarily pause or adjust therapy only if a clinician advises it
- Switch to a different statin if the symptom is persistent or clearly linked
Do not stop atorvastatin on your own if it’s been prescribed for cholesterol, heart disease, or stroke risk reduction.
Could something else be causing the appetite loss instead?
Often, yes. Appetite loss can be caused by many non-drug factors, including infections, stomach virus, gastritis/ulcer, depression, uncontrolled pain, thyroid problems, and medication interactions. If appetite loss started around the same time as atorvastatin, it could still be drug-related, but a clinician typically looks for other explanations too.
Are there alternatives if atorvastatin bothers your stomach?
If atorvastatin is the likely trigger, clinicians sometimes:
- Adjust the dose
- Change to another statin
- Use non-statin lipid-lowering options (depending on your cholesterol risk and lab results)
The best option depends on your cholesterol goals and cardiovascular history.
What info would help a clinician assess the cause?
If you can, note:
- When appetite loss began relative to starting atorvastatin (and whether it changed after dose changes)
- Any GI symptoms (nausea, pain, diarrhea/constipation)
- Any other new medications or supplements
- Recent liver-related symptoms (fatigue, dark urine, jaundice)
- Your most recent liver enzyme results (if available)
