Malabsorption may contribute to malnutrition in the elderly
Nutrition (Burbank, Los Angeles County, Calif.)
|January 26, 2010
Summary
Malabsorption affects 80% of elderly patients, contributing to malnutrition. This study found increased intestinal permeability in 10 elderly patients, linked to poor nutritional status and potential celiac disease.
Area of Science:
- Gerontology
- Gastroenterology
- Nutritional Science
Background:
- Malnutrition is prevalent in 80% of hospitalized elderly patients.
- Malabsorption is an under-explored factor contributing to elderly malnutrition.
- This study investigated nutritional status, mucosal permeability, and celiac disease in elderly rehabilitation patients.
Discussion:
- Increased intestinal permeability was identified in 10 out of 48 elderly subjects.
- Subjects with increased permeability had significantly lower Mini-Nutritional Assessment (MNA) scores, indicating higher malnutrition risk.
- Two subjects tested positive for tissue transglutaminase antibodies, suggesting potential celiac disease.
Key Insights:
- Elderly patients undergoing rehabilitation exhibit a high prevalence of altered intestinal permeability.
- Impaired mucosal permeability is strongly associated with malnutrition risk in this population.
- The findings highlight malabsorption as a significant, yet often overlooked, contributor to malnutrition in the elderly.
Outlook:
- Further research is needed to elucidate the specific causes of malabsorption in the elderly.
- Early screening for malabsorption could improve nutritional interventions and patient outcomes.
- Understanding malabsorption's role is crucial for optimizing nutritional support and drug efficacy in geriatric care.

Factors Influencing Drug Absorption: Disease States and Pharmacology
Multiple disease states can significantly influence the oral drug absorption process by affecting blood flow and the functionality of the gastrointestinal (GI) system. Various GI diseases, including conditions that alter GI motility, such as diarrhea, decreased acid secretions (achlorhydria), and infections, have been associated with reduced drug absorption.
Substances such as alcohol and specific drugs, including antineoplastics, can also negatively impact drug absorption. For instance,...

Overview of Protein Metabolism
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...

Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
Bioavailability: Influencing Factors
Bioavailability refers to the extent and rate at which a drug reaches systemic circulation in its active form. Extent refers to the amount of the drug that makes it into circulation, while rate is the speed at which it enters circulation. It is influenced by several factors critical for optimizing drug formulations, dosing regimens, and therapeutic outcomes.Physicochemical properties of drugs and formulationsThe solubility, stability, and dissolution rate of a drug significantly impact its...
Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Bone Disorders
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...
