Patient Reports / LoginPseudocholinesterase Deficiency: Causes and Effects on Your Health
Written by Medicover Team and Medically Reviewed by Dr Shankeshi Priyanka , Anesthesiologists
Table of Contents
Pseudocholinesterase deficiency is a rare genetic disorder that affects the body's ability to break down certain medications, particularly muscle relaxants commonly used during anesthesia.
The condition occurs when the body produces insufficient amounts of the pseudocholinesterase enzyme or produces an enzyme that does not function properly. This enzyme is responsible for metabolizing specific drugs, including succinylcholine and mivacurium.
When these medications are not broken down efficiently, they can remain active in the body for longer than expected, leading to prolonged muscle paralysis and breathing difficulties after surgical procedures.
Although many individuals are unaware they have the condition until exposed to these medications, early diagnosis and proper medical awareness are essential to prevent complications and ensure safe anesthesia management.
Types of Pseudocholinesterase Deficiency
Pseudocholinesterase deficiency can occur in inherited or acquired forms.
- Acquired Pseudocholinesterase Deficiency: Often results from liver disease, malnutrition, chronic illnesses, or exposure to certain medications and chemicals.
- Inherited Pseudocholinesterase Deficiency: A genetic condition passed through families due to mutations affecting the enzyme's production or function.
What Are the Symptoms of Pseudocholinesterase Deficiency?
The symptoms of pseudocholinesterase deficiency are usually noticed after exposure to certain anesthetic drugs during medical procedures.
- Prolonged Paralysis: Muscle paralysis lasting longer than expected after anesthesia.
- Respiratory Complications: Difficulty breathing independently after surgery.
- Muscle Weakness: Persistent weakness beyond the normal recovery period.
- Delayed Recovery: Extended time spent under medical observation after anesthesia.
What Causes Pseudocholinesterase Deficiency?
The primary cause of pseudocholinesterase deficiency is genetic mutations that affect the structure or function of the pseudocholinesterase enzyme.
Genetic Mutations
Several inherited mutations can reduce enzyme activity or prevent the enzyme from functioning properly. The condition is usually inherited in an autosomal recessive pattern.
Environmental Factors
Acquired pseudocholinesterase deficiency may develop due to:
- Liver disease
- Malnutrition
- Chronic infections
- Exposure to pesticides
- Certain medications
When Should You See a Doctor for Pseudocholinesterase Deficiency?
You should consult an anesthesiologist if you or a family member has experienced prolonged paralysis or delayed recovery following anaesthesia. Early identification can help prevent future complications during surgery.
A medical evaluation is also important if there is a family history of pseudocholinesterase deficiency or unexplained anesthesia-related complications.
- History of prolonged recovery after surgery
- Unexpected breathing difficulties following anesthesia
- Family history of pseudocholinesterase deficiency
- Concerns before undergoing a surgical procedure

How is Pseudocholinesterase Deficiency Diagnosed?
Diagnosis involves reviewing medical history, family history, and performing laboratory tests to evaluate enzyme activity.
- Blood tests to measure pseudocholinesterase enzyme activity
- Dibucaine inhibition test
- Genetic testing for inherited mutations
- Family history assessment
What is the Treatment for Pseudocholinesterase Deficiency?
There is currently no cure for pseudocholinesterase deficiency. Treatment focuses on preventing complications and providing supportive care when necessary.
Preoperative Planning
- Inform healthcare providers and anesthesiologists about the condition before surgery.
- Avoid anesthetic drugs metabolized by pseudocholinesterase.
Supportive Care
- Mechanical ventilation may be required until muscle function returns.
- Close monitoring in the recovery period.
Medications
- Drugs such as neostigmine may be used in selected situations to help reverse prolonged muscle relaxation.

What Are the Risk Factors for Pseudocholinesterase Deficiency?
Several factors can increase the likelihood of developing inherited or acquired pseudocholinesterase deficiency.
- Family history of the condition
- Genetic mutations affecting the enzyme
- Liver disease
- Malnutrition
- Exposure to certain chemicals or medications
What Are the Complications of Pseudocholinesterase Deficiency?
The main complications are related to the body's inability to metabolize specific anesthetic medications properly.
- Prolonged paralysis
- Respiratory failure requiring ventilation support
- Delayed recovery after surgery
- Extended hospital stays
- Anesthesia-related complications
Can Pseudocholinesterase Deficiency Be Prevented?
Inherited pseudocholinesterase deficiency cannot be prevented. However, awareness and proper medical planning can significantly reduce the risk of complications.
- Inform healthcare providers about the condition
- Consider family screening and genetic counseling
- Avoid medications known to trigger complications
- Manage underlying liver disease and nutritional deficiencies
Frequently Asked Questions
1. Is pseudocholinesterase deficiency inherited?
Yes. The inherited form is caused by genetic mutations and is usually passed down in an autosomal recessive pattern.
2. Can pseudocholinesterase deficiency cause problems during surgery?
Yes. It can cause prolonged paralysis and delayed recovery after receiving certain anesthetic medications, particularly succinylcholine and mivacurium.
3. Which doctor treats pseudocholinesterase deficiency?
An anesthesiologist, genetic specialist, or internal medicine physician may help diagnose, manage, and provide guidance regarding the condition.
4. Can blood tests detect pseudocholinesterase deficiency?
Yes. Blood tests can measure pseudocholinesterase enzyme activity and help confirm the diagnosis.
5. Should family members be tested?
Family members may benefit from genetic counseling and testing, especially when there is a family history of pseudocholinesterase deficiency.
6. What is pseudocholinesterase deficiency?
Pseudocholinesterase deficiency is a rare condition in which the body cannot properly break down certain muscle relaxants used during anesthesia, resulting in prolonged muscle paralysis.
7. What are the symptoms of pseudocholinesterase deficiency?
Most people have no symptoms until they receive specific anesthetic drugs. The main sign is prolonged muscle weakness or inability to breathe independently after anesthesia.
8. How is pseudocholinesterase deficiency diagnosed?
Diagnosis is made through blood tests that measure enzyme activity, dibucaine number testing, and sometimes genetic testing.
9. Can pseudocholinesterase deficiency be cured?
No. There is no cure for the inherited form, but the condition can be effectively managed by avoiding triggering medications and informing healthcare providers before surgery.
10. What medications should be avoided with pseudocholinesterase deficiency?
People with pseudocholinesterase deficiency should avoid certain anesthetic agents, particularly succinylcholine and mivacurium, unless specifically managed by an anesthesiologist familiar with the condition.
