Summary
Gastric surgery can lead to bone metabolic disorders in 30% of patients. The extent of stomach removed and the food passage reconstruction significantly influence bone health post-gastrectomy.
Area of Science:
- Gastroenterology
- Endocrinology
- Orthopedics
Context:
- Gastrectomy, a surgery for stomach conditions, can lead to silent bone metabolic disorders.
- Clinician awareness of post-gastrectomy bone complications remains insufficient.
Purpose:
- To investigate the impact of gastrectomy on bone metabolism.
- To analyze the influence of resected stomach volume and food passage reconstruction on bone health.
Summary:
- Bone metabolic disorders affect 30% of patients post-gastrectomy.
- Milder disorders observed with proximal/segmental gastrectomy versus total/distal.
- Physiological food passage routes correlate with better bone metabolism outcomes.
- Animal models corroborated clinical findings.
Impact:
- Highlights the correlation between remnant stomach volume, food passage route, and bone metabolic disorders.
- Emphasizes the need for increased clinical awareness and proactive management of bone health after gastrectomy.

Inborn Errors of Metabolism
1.0K
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Bone Disorders
7.6K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Overview of Protein Metabolism
4.6K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
1.6K
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Gastrointestinal Motility Disorders
1.5K
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Disorders of the Skeletal Muscle
2.3K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
