Sample Case Study 1 — Bipolar Disorder During Rapid Ketogenic Transition

 

Clinical Context

A female patient with bipolar disorder was stable on two mood stabilizers. Over time, she developed significant weight gain related to medication-associated metabolic effects and increased carbohydrate cravings. During a routine primary care visit, laboratory evaluation revealed an elevated C-reactive protein (CRP) level of 11 mg/L, raising concern for increased cardiovascular risk.

Motivated to reduce this risk, the patient independently initiated a ketogenic diet. She selected a highly restrictive online plan modeled after therapeutic ketogenic protocols used in epilepsy (inpatient) and implemented it without medical consultation.

​

Initial Course

Within 48 hours, urine ketone testing indicated high ketone production. The patient initially interpreted this as a positive response.

She subsequently developed:

• Polyuria

• Increased thirst

• Fatigue

• Leg cramps

• Mild agitation

These symptoms were attributed by the patient to “keto flu.”

Case without Structured Between-Visit Monitoring Guidance from Providers

​

Primary Care (via assistant)

• Input: Patient-reported fatigue, polyuria, discomfort

• Interpretation: Dietary adaptation / inadequate ketosis

• Recommendation: Add exogenous ketones

• Constraint: No visibility into severity of symptoms or dietary restriction

​​

Psychiatry

• Input: Agitation and reduced stability during visit

• Interpretation: Early mood destabilization

• Recommendation: Increase mood stabilizer by 50%

• Constraint: No visibility into metabolic changes​

​​

Contextual Limitation

The full sequence of events was not visible within any single clinical encounter. In addition, the patient had difficulty articulating symptoms and context clearly.

​

Clinical Interpretation

The patient was undergoing a rapid metabolic transition characterized by:

• Abrupt carbohydrate restriction

• Likely caloric deficit

• Increased ketone production

• Limited early capacity for ketone utilization

• Ongoing reliance on glucose

Associated physiological changes likely included:

• Increased diuresis and natriuresis

• Reduction in circulating insulin

• Progressive electrolyte loss, particularly sodium

​

Potential Outcome Without Context Integration

If both recommendations were followed concurrently:

• Worsening electrolyte imbalance

• Increased symptoms 

• Reduced clarity in clinical decision-making

• Increased likelihood of escalation of care

​

Case with Structured Between-Visit Monitoring (CLIP) Early Detection and Triage

Following onset of symptoms, the patient submitted real-time updates including diet, symptoms, and subjective state to CLIP.

Clinical pattern recognition identified:

• Electrolyte imbalance consistent with rapid ketogenic adaptation

• Elevated stress and agitation based on language patterns

​

Interventions (Within Predefined Limits)

• Adjustment of fluid intake behavior (avoid rapid intake)

• Increased dietary sodium 

• Identification of medication-related sodium effects

• Magnesium glycinate supplementation

• Dietary potassium through food sources

​

Dietary Correction

Analysis of the patient’s meal plan identified:

• Excessive carbohydrate restriction beyond outpatient standards

• Unintentional caloric restriction

Adjustments were made to ensure:

• Adequate caloric intake

• Sufficient protein intake

• Modified, sustainable dietary approach

​

Clinical Communication

A structured clinical summary was generated, including:

• Timeline of dietary change

• Symptom progression

• Identified risks

• Interventions implemented

This summary was available for both primary care and psychiatry.

​

Ongoing Monitoring

Daily updates enabled:

• Tracking of symptom resolution

• Monitoring of diet and sleep patterns

Additional patterns identified:

• Reduced sleep duration associated with ketogenic transition

• Potential risk to mood stability

Interventions included:

• Reinforcement of consistent sleep timing

• Alignment of meal timing with circadian rhythm

​

Outcome

Within approximately one week:

• Improvement in fatigue, thirst, and cramps

• Reduction in agitation

Over subsequent two months:

• Improved sleep architecture and consistency

• Weight loss (~12 lbs)

• Initiation of structured exercise program with a personal trainer

​​​​

Summary

In the absence of structured visibility between visits, clinical decisions were made using partial and non-overlapping information.

With structured monitoring, evolving physiological and behavioral patterns were identified early, allowing for targeted, low-risk interventions and improved continuity of care.
