PBH Management
PBH Management
The primary goals of PBH management are to reduce the frequency and severity of hypoglycemic episodes and support patient safety and quality of life.1 However, management can be challenging due to the absence of standardized care pathways and the limited availability of evidence‐based therapeutic options.2
Multidisciplinary collaboration and research are needed to refine care pathways and expand available treatment options in this evolving area.2
“I think for medical providers managing PBH, one hardship is trying to help patients figure it out because everyone's experience seems so different. Even within my own self, from day to day, it's different. I can eat one food today and my blood sugar stays stable all day long. Tomorrow I can eat the exact same thing and it will go crazy. The uncertainty and anxiety that follows that is the worst part of PBH.”
— Cindy, person with PBH
Medical Nutrition Therapy
Medical Nutrition Therapy in PBH
Medical nutrition therapy (MNT) plays a central role in PBH management, with dietary strategies designed specifically to address the condition’s hypoglycemic patterns.1,2 Approaches are typically adapted to patients’ symptom patterns, nutritional status, and activity levels, with adjustments made over time based on clinical response.1,2
In PBH, MNT involves more than dietary composition alone. It typically includes ongoing monitoring of symptoms and glucose patterns, patient education on recognizing and managing hypoglycemia, and safety planning for daily activities, often with guidance from a registered dietitian experienced in PBH management.1–3
Even with careful tailoring, responses to MNT can vary. Hypoglycemia may remain unpredictable and incompletely controlled despite sustained adherence.1,2
Key components of MNT for PBH:1,2,4
Meal timing and composition:
Smaller, more frequent meals and individualized macronutrient composition, with attention to carbohydrate glycemic profile, may help stabilize postprandial glucose levels.
Dietary and beverage considerations:
Alcohol, caffeine, and liquids consumed alongside meals may contribute to symptom onset and are worth reviewing as part of an individualized assessment.
Nutritional monitoring:
Ongoing assessment of nutritional status, ideally in collaboration with a registered dietitian who is experienced with PBH, may help to ensure that dietary strategies support both nutritional needs and daily life.
Planning for acute episodes:
An individualized plan for recognizing and managing acute hypoglycemia, including appropriate use of rapid-acting carbohydrates and strategies to limit rebound episodes, may help to support patient safety.
Patient education:
Patients may have limited confidence or familiarity with interpreting food labels, which can make it more difficult to select appropriate food options. Structured education may help patients apply dietary strategies more confidently in everyday life.
“Food is essential but mostly unpleasant. It is monotonous as I must pretty much adhere to exactly the same foods and schedule each day. When that schedule is disrupted, it is rarely without negative consequences.”
— Elizabeth, person with PBH
Pharmacotherapy
Pharmacotherapy in PBH
While medical nutrition therapy (MNT) is the foundation of PBH management, it may not be sufficient for all individuals living with PBH.1,2
In these circumstances, pharmacotherapy is sometimes considered; however, there are currently no medications approved for the treatment of PBH.1,2 Available agents are used off-label, and supporting evidence is derived primarily from small studies and clinical experience.2
The absence of approved therapies reflects a significant unmet need, and research is ongoing to better define effective strategies for this patient population.2
Continuous glucose monitoring
Continuous Glucose Monitoring and PBH
Continuous glucose monitoring (CGM) can support recognition of postprandial glucose patterns and dietary triggers, while real-time alerts may enable earlier intervention, particularly in individuals with hypoglycemia unawareness.1,2
Considerations for use of CGM in PBH:1,5
- Low sensor readings alone do not establish a diagnosis of PBH
- Limitations in accuracy at low glucose ranges
- Variable insurance coverage and access
- Potential psychological impacts, such as increased anxiety or distress, which may influence suitability for some patients
Representative CGM Pattern in PBH

Fasting normoglycemia1
PBH typically presents with postprandial hypoglycemia, most often occurring 1–3 hours after meals. Fasting hypoglycemia is not a typical feature.
Early postprandial glucose rise1,2
Glucose levels may rise rapidly after meals due to accelerated nutrient transit into the intestine, particularly following ingestion of high‑glycemic carbohydrates.
Hypoglycemic event1,2,6
Multiple mechanisms collectively contribute to an exaggerated postprandial insulin response, leading to a rapid glucose decline and hypoglycemia. Symptoms are broadly classified as autonomic or neuroglycopenic and typically emerge in a hierarchical pattern as blood glucose falls.
A daily glycemic pattern1
Hypoglycemic episodes may occur multiple times in a single day. In response, some patients may consume high-glycemic carbohydrates to relieve symptoms, leading to another spike in glucose levels followed by recurrent hypoglycemia, contributing to a “glycemic roller coaster” pattern.

“One of the biggest changes that has helped me manage my PBH has been using a continuous glucose monitor (CGM), along with continuing regular finger-prick testing to confirm readings. That combination has been important for both my awareness and safety.”

MANAGEMENT CONSIDERATIONS
Considerations in PBH Management
Managing PBH can be complicated by a range of factors.1 Physiological changes, treatment demands, and social, occupational, and emotional considerations may all influence how patients experience symptoms and engage with management strategies:1
Physiological considerations
Altered gastric anatomy, food intolerance, gastrointestinal symptoms, and potential nutritional deficiencies may influence how patients tolerate or implement dietary and medical strategies.
Management burden
Management may require sustained behavioral adaptation, regular glucose monitoring, meal planning, and attention to symptom timing. Medication regimens and device-related alerts can add ongoing practical and cognitive demands.
Social context
Dietary recommendations may not always align with cultural norms, family practices, or social occasions. Navigating shared meals and celebrations may require additional planning and support.
Occupational considerations
Frequent meals, glucose monitoring, or acute treatment of hypoglycemia may be difficult to accommodate. Cognitive effects or post-episode fatigue may further affect occupational functioning.
Financial considerations
Costs related to clinic visits, blood glucose monitoring, recommended dietary changes, and potential impacts on income may introduce financial strain.
Emotional impact
Recurrent and unpredictable hypoglycemia may contribute to stress and concerns about safety outside the home. For some patients, delayed diagnosis or persistent symptoms, despite adherence to management strategies, may compound frustration.
REFRACTORY Options
Surgical Management in PBH: A Last Resort Option
Given the potential risks and complications associated with surgical procedures to manage PBH, these approaches are reserved for severe cases that are medically refractory to dietary and pharmacologic management or complicated by hypoglycemia unawareness.2
