Summary
Lactose intolerance in older adults requires a personalized approach, focusing on clinical evaluation over testing. Avoiding overly restrictive diets is crucial for maintaining nutritional status in the elderly.
Area of Science:
- Geriatrics
- Gastroenterology
- Nutritional Science
Background:
- Lactose malabsorption and intolerance are prevalent conditions with diagnostic challenges in the elderly.
- Older adults face risks of malnutrition due to cognitive impairment, appetite loss, dysphagia, and poor oral health.
Purpose of the Study:
- To review current knowledge, concerns, and clinical practice impacts of lactose malabsorption and intolerance in the elderly.
- To address the debate surrounding optimal diagnostic and management strategies for lactose intolerance in advanced age.
Main Methods:
- This review synthesizes current literature on lactose intolerance in older adults.
- Focuses on clinical evaluation and nutritional implications rather than solely diagnostic testing.
Main Results:
- Dairy product reduction in older adults can lead to inadequate protein and mineral intake, affecting bone and muscle health.
- Lactose malabsorption testing can be challenging and potentially uninformative in older populations.
- Clinical assessment is vital to differentiate lactose intolerance from other conditions with similar symptoms.
Conclusions:
- Management of lactose intolerance in the elderly necessitates a personalized strategy.
- Prioritizing adequate nutritional status is essential, advocating against overly restrictive dietary measures.

01:27Glucose Transporters
22.7K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

01:25Factors Influencing Drug Absorption: Disease States and Pharmacology
495
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,...

01:21Drugs for Treatment of Constipation-Predominant IBS
157
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

01:19Oral Hypoglycemic Agents: α-Glucosidase Inhibitors
173
α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
