Who are Most Affected by Gastroparesis – Are You at Risk?

Gastroparesis is a chronic digestive disorder where the stomach’s ability to empty food into the small intestine is slowed down or impaired. This condition occurs when the muscles in the stomach, which are supposed to contract and push food through the digestive tract, don’t function properly due to nerve damage or other underlying factors. As a result, food lingers in the stomach longer than it should, leading to a range of uncomfortable symptoms.

Symptoms of Gastroparesis

• Nausea
• Vomiting
• Early Satiety
• Abdominal Pain
• Bloating
• Loss of Appetite
• Weight Loss
• Acid Reflux
• Erratic Blood Sugar Levels

Why is Understanding Gastroparesis Important?

1. Early Detection: Knowing who is most affected enables healthcare professionals and patients to identify the condition early.
2. Better Treatments: Understanding the underlying causes can pave the way for improved treatment options and management strategies.
3. Enhanced Quality of Life: Exploring and implementing effective treatments can help patients gain better control over their symptoms and improve their overall quality of life.

Who are Most Affected by Gastroparesis?

Gastroparesis, a condition marked by delayed gastric emptying, impacts a diverse group of people, but certain demographics are notably more affected. Understanding these groups helps to better address the challenges of managing and treating this complex disorder.

1. Gender Disparity

Gastroparesis disproportionately affects women, with studies revealing that approximately 68.5% of those diagnosed are female. This significant gender gap suggests that hormonal differences or other gender-specific factors may play a role, although the precise reasons remain under investigation.

2. Age Factors

While gastroparesis can develop at any age, it is most commonly observed in adults over 30 years old. The incidence tends to rise with age, likely due to the cumulative impact of risk factors such as diabetes and a history of abdominal surgeries. Younger individuals can also be affected, but they are less common cases.

3. Ethnic Disparities

When looking at gastroparesis across different ethnic groups, Caucasians appear to be the most commonly affected demographic. However, recent studies highlight that a significant portion of patients also come from South Asian and East Asian backgrounds, particularly individuals of Indian, Pakistani, Bangladeshi, and Chinese descent.

This emerging data suggests that while gastroparesis might appear more frequently in Caucasian populations, it’s important to acknowledge its impact on a broader range of ethnicities. Understanding these patterns can aid in creating more culturally sensitive approaches to diagnosis and treatment.

4. Underlying Health Conditions

Several health conditions notably increase the risk of developing gastroparesis:

• Diabetes: This is the leading cause, accounting for about 30% of gastroparesis cases. Persistent high blood sugar levels can damage the vagus nerve, which is crucial for stomach muscle function.
• Neurological Disorders: Conditions such as Parkinson’s disease and multiple sclerosis are linked to gastroparesis due to their effects on nerve function. These disorders can impair the nerves that control gastric motility, leading to delayed emptying.
• Post-Surgical Patients: Individuals who have undergone abdominal surgeries may experience nerve damage affecting gastric function, thus increasing their risk of gastroparesis.

5. Prevalence and Public Health Impact

Recent data indicates that gastroparesis affects approximately 267.7 per 100,000 adults in the U.S., underscoring its significance as a public health concern. The condition’s prevalence highlights the need for increased awareness and more effective management strategies.

By focusing on these demographics, healthcare providers can tailor their approach to treatment and support, ensuring that individuals who are most at risk receive the care they need.

Why are Women Most Affected by Gastroparesis?

1. Hormonal Fluctuations: Female hormones like estrogen and progesterone can slow down digestion, especially during certain phases of the menstrual cycle, potentially contributing to delayed gastric emptying.
2. Autoimmune Disorders: Women are more prone to autoimmune conditions, such as scleroderma, which can damage nerves controlling stomach muscles, increasing the risk of gastroparesis.
3. Surgical Risk: Women often undergo abdominal or gynecological surgeries, which may damage the vagus nerve, a key player in stomach function.
4. Stress and Anxiety: Women tend to experience higher levels of stress, which can worsen digestive issues, including gastroparesis

Root Causes of Gastroparesis

1. Idiopathic Gastroparesis

• Nearly 40% of gastroparesis cases fall under this category, where no clear cause is identified.
• Despite thorough testing, the underlying reason remains elusive, making it difficult to target specific treatments.

2. Diabetes Mellitus

• A significant contributor to gastroparesis, diabetes accounts for around 30% of cases.
• High blood sugar levels over time can damage the vagus nerve, which controls stomach muscles, leading to delayed gastric emptying.

3. Viral Infections

• Certain viral infections, such as norovirus, can attack the stomach’s nerve network, causing or worsening gastroparesis by impairing normal gastric function.

5. Medications

• Some medications, particularly narcotics and specific antidepressants, are known to slow gastric emptying.
• These drugs can either trigger symptoms or aggravate existing gastroparesis.

6. Autoimmune Disorders

• Autoimmune conditions like scleroderma can lead to immune system attacks on the body’s nerves, including those that regulate stomach function, resulting in gastroparesis.

7. Surgical Complications

• Surgeries involving the stomach or esophagus may inadvertently damage the vagus nerve, disrupting the stomach’s ability to contract and move food through the digestive tract efficiently.
• This nerve damage is a known trigger for gastroparesis symptoms.

Treatment and Management

1. Dietary Modifications:

• Focus on more frequent and smaller meals to ease digestion.
• Reduce fat and fiber intake, as they slow down gastric emptying.
• Opt for nutrient-dense, low-fat, and low-fiber foods to manage symptoms effectively.

2. Medications:

• Prokinetic agents (e.g., metoclopramide) stimulate stomach contractions to improve gastric motility.
• Antiemetics help control nausea and vomiting, offering relief from common gastroparesis symptoms.
• These medications should be taken under medical supervision for best results.

3. Surgical Options:

• Gastric electrical stimulation (GES): A device is implanted to send electrical impulses to stomach muscles, improving motility.
• G-POEM (gastric peroral endoscopic myotomy): A procedure where specific stomach muscles are cut to enhance gastric emptying.
• Used for severe cases that where other treatments don’t work.

Recent Advances in Gastroparesis Research
