Case Report: Lactation Ketoacidosis Can Complicate the Ketogenic Diet

Area of Science:

• Metabolic disorders
• Nutritional science
• Critical care medicine

Background:

• Ketoacidosis is a serious metabolic disturbance characterized by elevated ketone bodies.
• Common causes include diabetes, alcoholism, and starvation.
• Ketogenic diets, while popular for weight loss, restrict carbohydrates, increasing ketone production.

Observation:

• A 32-year-old lactating woman, 8 weeks postpartum, presented with symptoms of pneumonia.
• She was adhering to a ketogenic diet and had no prior history of diabetes or substance abuse.
• Pneumonia was diagnosed and treated, but she subsequently developed severe ketoacidosis.

Findings:

• The patient's ketoacidosis was triggered by community-acquired pneumonia superimposed on a ketogenic diet during lactation.
• Treatment involved antibiotics for pneumonia and a dextrose solution for acidosis.
• The case underscores the potential dangers of ketogenic diets in vulnerable populations.

Implications:

• Physicians must consider ketogenic diet as a risk factor for ketoacidosis, particularly with additional physiological stressors.
• Ketogenic diets may pose significant risks during lactation, potentially increasing maternal morbidity.
• Further research is warranted to assess the safety and long-term effects of ketogenic diets in lactating women.
