Adrenaline Surges in ME (Myalgic Encephalomyelitis)

Purpose

To explain what adrenaline surges are in ME, how they affect patients, how to recognise them, and why they can lead to worsening symptoms despite temporarily increased activity.

Key Points

1. What Are Adrenaline Surges?

• Adrenaline surges occur when the body is placed under physiological stress
• They temporarily allow individuals with ME to function above their normal limits
• While this may appear beneficial, it comes at a significant cost
• These surges can lead to severe and prolonged worsening of symptoms afterward

2. The “False Energy” Effect

• Adrenaline can create a temporary sense of:
  • Increased energy
  • Reduced fatigue
  • Improved ability to complete tasks
• This is misleading and does not reflect real improvement
• It is often followed by a significant relapse

3. Common Signs of an Adrenaline Surge

• Fast, loud, or continuous talking
• Feeling “wired,” overactive, or unusually driven
• Difficulty resting or sleeping
• Increased ability to stand or sit upright beyond normal limits
• Shaking, twitching, or muscle weakness
• Sweating, shortness of breath, or rapid pulse
• Headaches, pressure in the head or behind the eyes
• Visual sensitivity or difficulty keeping eyes open
• Sudden changes in hearing (e.g., ringing)
• Increased thirst or hunger, especially for carbohydrates
• Changes in skin colour (e.g., pale or mottled extremities)

4. Why Adrenaline Surges Happen

• The body releases adrenaline to cope with overexertion or stress
• This occurs when activity exceeds the body’s limited energy capacity
• It can happen during:
  • Physical activity
  • Cognitive effort
  • Emotional stress
• Large or demanding tasks are common triggers

5. Misinterpreting Improvement

• Temporary increases in activity after exertion are often mistaken for recovery
• True improvement does not occur immediately after overexertion
• What appears as recovery is often just adrenaline masking underlying illness

6. Consequences and Risks

• Activities completed during adrenaline surges can lead to:
  • Severe symptom relapse
  • Delayed worsening (often 24–72 hours later)
• Repeated use of adrenaline “overdrive” can significantly harm long-term health

7. Management and Prevention

Avoid Overexertion

• Stay within consistent energy limits
• Avoid pushing beyond capacity, even during “good” periods

Rest and Recovery

• Adrenaline surges may require:
  • Extended periods of complete rest (often several days)
• Reducing stimulation (noise, conversation, activity) is important

Structured Communication

• Limit prolonged or unexpected conversations
• Plan communication times to conserve energy

Pacing Approach

• Focus on activities that can be sustained regularly without causing relapse
• Recognise that both physical and mental activity contribute to energy use

Target Audience

• Individuals living with ME/CFS
• Caregivers and family members
• Healthcare professionals
• Support organisations and advocacy groups
• General public seeking understanding of ME

Overall Outcome

Adrenaline surges in ME represent a temporary and misleading increase in functional capacity that often results in significant long-term harm. Recognising these surges and understanding their impact is essential for effective pacing, symptom management, and preventing relapse. Careful energy management and rest are key to maintaining stability and improving quality of life.
