Study Notes

Kidney Disease

Obesity is linked to glomerulopathy and chronic kidney disease (CKD).
Elevated albumin levels in urine of obese patients can be an indicator of kidney failure due to obesity.

Liver Disease

Obesity is associated with nonalcoholic fatty liver disease (NAFLD).
NAFLD involves hepatic steatosis, fibrosis, and cirrhosis.
Obesity and insulin resistance are the primary causes of NAFLD.

Infertility

Obesity is linked to infertility, particularly in women.
Excess weight leads to excessive androgen excretion, insulin resistance, and hyperinsulinemia.
Increased androgen levels can cause ovarian dysfunction and, consequently, infertility.

Gastroesophageal Reflux Disease (GERD)

The exact relationship between obesity and GERD is not fully understood.
Potential causes of GERD in obese individuals include increased fat intake, smoking, alcohol consumption, and potentially a decrease in Helicobacter pylori infection.

Cancer

Obesity is associated with an increased risk of certain cancers.
Adipose tissue converts fatty acids into specific signaling lipids that stimulate cancer cells through paracrine or autocrine interactions.
These interactions trigger the upregulation of the enzyme monoacylglycerol lipase (MAGL), which plays a crucial role in fat synthesis.
This upregulation occurs through various oncogenic signaling pathways, contributing to cancer development.

Diabetes Type 2

Approximately 50% of patients diagnosed with obesity have diabetes.
15% of obese patients develop type 2 diabetes within 6 years.
Long-term complications of type 2 diabetes include heart and vascular diseases, retinopathy, nephropathy, and neuropathy.
Preventing type 2 diabetes in obese patients can prevent numerous comorbidities.

Metabolic Syndrome

Defined as a combination of at least three of the following: central obesity, high triglyceride (TG) serum concentrations, low high-density lipoprotein (HDL) serum concentrations, high cholesterol concentrations, hypertension, and elevated blood sugar levels after eating.
Can lead to left ventricular hypertrophy and diastolic dysfunction, associated with heart and vascular diseases.
Obese patients are 3.5 times more likely to develop hypertension.

Breathing Issues

Obesity is associated with obesity hypoventilation syndrome (OHS, also known as Pickwickian syndrome).
People with obesity often have difficulty breathing deeply.
OHS is a combination of obesity, hypoxia (low oxygen levels in the arterial blood), and hypercapnia (high carbon dioxide levels in the arterial blood).
Many people with OHS experience brief pauses in breathing during the night (obstructive sleep apnea syndrome, OSAS).
The soft palate collapses during sleep in these individuals.
A sleep mask can help reduce symptoms.
The prevalence of hypercapnia in the general Western population is 0.3% to 0.4%, but 10% to 20% in obese patients (with sleep apnea/OHS).
A higher BMI increases the risk of asthma due to adipose tissue obstructing the airways.
