Possible Causes
Generally, Lethargic can be related to:
- Drug-Induced Hypersensitivity Syndrome
Drug-induced hypersensitivity syndrome, also known as drug rash with eosinophilia and systemic symptoms (DRESS), is a severe reaction to a drug marked by fever, rash, and multiorgan failure. It can happen between 1-8 weeks after taking the drug. Drugs that most often cause DRESS include certain anti-seizure medications like carbamazepine, phenytoin, and phenobarbital, as well as allopurinol, which is used for gout.
- Rabies
Rabies is a deadly viral disease that can spread to people and animals through bites or scratches from infected animals. It is commonly found in wild animals like stray dogs, bats, raccoons, skunks, and foxes. The rabies virus travels through nerve cells to the brain, where it multiplies quickly, causing severe inflammation of the brain and spinal cord, often leading to death.
- Hyperemesis Gravidarum
A severe form of morning sickness, where patients have significant vomiting and are typically unable to keep much food or fluids down. They can lose weight and become very dehydrated. The exact cause is unclear, but it's thought to be related to levels of pregnancy hormones (β-hCG and estrogen). Early treatment of morning sickness can help prevent progression to this severe form. There is typically no harm to the developing baby from this condition, but it is important to maintain normal hydration and weight in the mom.
- Urea Cycle Disorder
- Alcohol-related liver disease
- Watery Diarrhea, Hypokalemia, and Achlorhydria (WDHA) Syndrome
- Acute Disseminated Encephalomyelitis
Related Serious Diseases
Sometimes, Lethargic may be related to these serious diseases:
- Cyclic Vomiting
A condition with repeated and severe vomiting. Patients may become very unwell due to dehydration and starvation. The exact cause is unknown, but known triggers include emotional stress, anxiety, or viral illnesses.
- Heatstroke
- Sepsis
Doctor's Diagnostic Questions

- Do you feel you fatigued?
- How long have you felt fatigued and unwell this time?
- How would you rate your current level of fatigue?

I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
