Carbohydrate Metabolism

Carbohydrate Metabolism

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

Pathophysiology of Diabetes

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...

Diabetes Mellitus: Type 2 and Gestational

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes: Symptoms, Diagnosis, and Complications

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is based on...

Insulin: Dosing Regimen and Adverse Effects

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Summary

Gastric bypass surgery leads to less weight loss in diabetic patients, but significantly improves diabetes and hypertension. Patients with diabetes mellitus (DM) should still consider bariatric surgery for substantial health benefits.

Background:

Weight loss surgery is known to improve glycemic control in patients with diabetes.
Investigating the impact of diabetes mellitus (DM) on post-gastric bypass surgery outcomes is crucial.

Purpose of the Study:

To determine if diabetes mellitus (DM) adversely affects weight loss after gastric bypass surgery.
To compare outcomes in patients with and without DM undergoing gastric bypass.

Main Methods:

A retrospective analysis of gastric bypass surgery patients.
Demographics and outcomes were compared between patients with and without DM.
DM severity was categorized into diet-controlled, oral hypoglycemic agents, and insulin-dependent.

Main Results:

Patients with DM were older and had more comorbidities (hypertension, sleep apnea) than those without DM.
At 1 year post-surgery, the DM group showed a lower percentage of excess weight loss (60.8%) compared to the non-DM group (67.6%).
Despite lower weight loss, significant DM resolution occurred (89.8% in diet-controlled, 82.7% in oral hypoglycemic, 53.3% in insulin-dependent).

Conclusions:

Diabetes mellitus is associated with more comorbidities but does not preclude successful gastric bypass surgery.
Patients with DM experience less weight loss but achieve significant improvements in diabetes and hypertension resolution.
Gastric bypass surgery is a viable option for patients with DM, offering substantial health benefits beyond weight loss.
