Pathological hypersecretory conditions

Share on Pinterest

Stomach acid, or gastric acid, is important in digesting food. The main component of stomach acid is hydrochloric acid. In pathological hypersecretory conditions, the stomach can produce more acid than necessary for digestion, which may lead to uncomfortable symptoms and complications.

In the following sections, we will look at some examples of pathological hypersecretory conditions that often arise due to underlying medical conditions, including their symptoms and treatment.

Zollinger-Ellison syndrome (ZES) is a rare disorder that can occur when a gastrin-secreting tumor of the pancreas or duodenum (gastrinoma triangle) stimulates the stomach’s acid-secreting cells.

Symptoms

The main symptom of Zollinger-Ellison syndrome includes having multiple tumors in the endocrine system and the pancreas.

Other signs and symptoms include:

• persistent abdominal pain
• chronic diarrhea
• heartburn
• gastroesophageal reflux disease (GERD)
• peptic ulcers that do not heal despite treatment

Treatment

Various types of treatment are available for Zollinger-Ellison syndrome, with the main focus being surgery to remove the tumors and ulcers. Additional treatments may include:

• proton pump inhibitors (PPIs) to reduce gastric acid production
• chemotherapy or embolization to prevent tumor growth
• medications to manage symptoms and prevent complications

Helicobacter pylori (H. pylori) is a type of bacteria that infects the stomach and small bowel, causing inflammation. It affects up to 50% of the population worldwide and can increase the risk of ulcers, gastritis, and cancer.

Symptoms

While individuals with H. pylori often have no symptoms at first, when gastritis and peptic ulcer disease have set in, symptoms may include:

• abdominal pain
• nausea and vomiting
• bloating
• loss of appetite
• dyspepsia

Treatment

Doctors can treat most H. pylori infections successfully with antibiotics, which can eradicate H. pylori bacteria.

However, research suggests that some H. pylori infections are becoming resistant to certain antibiotics, meaning H. pylori is able to survive antibiotic treatment. A doctor may prescribe alternative treatment, including:

• proton pump inhibitors (PPIs) to reduce gastric acid production
• histamine receptor blockers
• antacids to relieve symptoms

Doctors may treat H. pylori in children and adolescents with a proton pump inhibitor (PPI) and two different antibiotics. This treatment should last 14 days. However, if it is not successful, the doctor may attempt to increase the dosages or substitute the antibiotics.

Short-bowel syndrome (SBS) is a set of symptoms that occur due to a shortened small intestine. It can lead to the need for nutritional and fluid supplements, as the small intestine cannot absorb enough nutrients from foods and drinks, a condition called malabsorption.

SBS is a rare condition affecting approximately 3 to 4 in every 1 million people.

Symptoms

Symptoms of short-bowel syndrome can be mild or severe and include:

• diarrhea
• malnutrition
• fatigue
• steatorrhea
• weight loss
• dehydration

Treatment

There are numerous treatment options for SBS. They include:

• total parenteral nutrition (TPN)
• nutritional support, including additional supplements to avoid vitamin and mineral deficiencies
• medications to promote nutrient absorption
• surgical interventions to lengthen the intestine
• intestinal transplant if an individual has serious complications and cannot continue using a TPN

Chronic renal failure, also known as chronic kidney disease (CKD) is a long-term condition that causes a gradual loss of kidney function over several years.

CKD is a common condition. The National Kidney Foundation reports CKD affects approximately 37 million people in the United States. It is usually associated with getting older; however, it can affect anyone.

Symptoms

There are usually no symptoms of kidney disease in the early stages, and it often goes undetected and undiagnosed until the condition is well advanced. At a more advanced stage, symptoms can include:

• hypertension, or high blood pressure
• anemia
• fatigue
• edema, or swollen feet, hands, and ankles
• shortness of breath
• nausea and vomiting
• blood in urine
• decreased mental alertness

Treatment

Damage to a person’s kidneys from CKD is usually permanent. Treatment for CKD aims to stop or slow the progression of kidney dysfunction, reduce the risk of complications, and help alleviate symptoms.

Treatment options vary depending on the underlying cause and symptoms, and may include:

• lifestyle changes
• dietary modifications to reduce the workload on the kidneys
• medications to manage symptoms and complications such as high blood pressure and high cholesterol
• dialysis to replicate some of the kidney’s functions which may be necessary in advanced stages
• kidney transplant in advanced stages

Antral g-cell hyperplasia and antral gastrin cell hyperfunction (AGCH) are rare causes of duodenal ulcers associated with non-tumor hypergastrinemia and acid hypersecretion.

They cause higher levels of gastrin, an important hormone of the digestive system, which assists gastric acid secretion and aids digestion. The G cells of the antrum of the stomach release gastrin.

Symptoms

Symptoms of antral G cell hyperplasia and AGCH may include:

• abdominal pain
• acid reflux
• nausea and vomiting
• peptic ulcers

Treatment

Treatment for antral G cell hyperplasia and AGCH may include:

• proton pump inhibitors (PPIs) to reduce gastric acid production
• medications to suppress gastrin secretion
• surgery in severe cases

Retained gastric antrum syndrome is a rare postgastrectomy syndrome. It occurs when stomach function changes occur following surgery, such as gastrectomy or gastric resection, disrupting digestion and gastric emptying.

Symptoms

Symptoms of retained gastric antrum syndrome may include:

• abdominal pain and discomfort
• bloating
• nausea and vomiting
• delay in gastric emptying

Treatment

Treatment for retained gastric antrum syndrome may include:

• medications to promote gastric emptying
• dietary modifications, such as small, frequent meals
• surgical interventions to correct underlying anatomical issues

In addition to these conditions, other hypersecretory states include:

• peptic ulcer disease (PUD)
• gastroesophageal reflux disease (GERD)
• gastrointestinal bleeding

Factors such as stress, certain medications, and genetics can contribute to these pathological hypersecretory states. It is essential for healthcare professionals to conduct thorough evaluations to determine the underlying cause and create the right treatment plans.

The outlook for individuals with pathological hypersecretory conditions varies depending on the underlying cause, severity of symptoms, and response to treatment. With early diagnosis, treatment, and appropriate management, many patients can effectively manage their symptoms and prevent complications, leading to an improvement in quality of life.

Pathological hypersecretory conditions involve excessive production of gastric acid, leading to various symptoms and complications. These conditions require targeted treatments aimed at reducing acid secretion, managing symptoms, and addressing underlying causes.

Proper medical management of these challenging conditions can help individuals live fulfilling lives. Where possible, early diagnosis and proactive management are key to achieving the best outcomes for those affected by pathological hypersecretory conditions.
