Hidden risks and prevention opportunities following surgical interventions
Imagine a scenario: a woman successfully undergoes complex gastrointestinal surgery, recovers, and it seems the worst is behind her. But months or even years later, new concerning symptoms appear—unexplained fatigue, weight fluctuations, elevated blood pressure. What's happening? It turns out that surgical interventions on digestive organs can trigger a cascade of metabolic changes that manifest not immediately, but in the long term.
Metabolic syndrome is a cluster of interconnected conditions including abdominal obesity, elevated blood pressure, insulin resistance, and dyslipidemia.
After various gastroenterological surgeries, the risk of developing metabolic syndrome in women increases by 25-40% 7 .
Metabolic syndrome represents a complex of interrelated disorders that significantly increase the risk of cardiovascular diseases, type 2 diabetes, and other serious health problems. According to modern understanding, metabolic syndrome is based on insulin resistance—reduced sensitivity of cells to insulin, leading to impaired glucose absorption and compensatory increase in production of this hormone 5 .
| Criterion | IDF | NCEP ATP III | AHA |
|---|---|---|---|
| Obesity | WC >80 cm (women) | WC >88 cm (women) | WC >88 cm (women) |
| Triglycerides | ≥150 mg/dL | ≥150 mg/dL | ≥150 mg/dL |
| HDL Cholesterol | <50 mg/dL | <50 mg/dL | <50 mg/dL |
| Blood Pressure | ≥130/85 mmHg | ≥130/85 mmHg | ≥130/85 mmHg |
| Fasting Glucose | ≥100 mg/dL | ≥100 mg/dL | ≥100 mg/dL |

Any surgical intervention on the gastrointestinal tract—whether gastric resection, intestinal surgery, or gallbladder surgery—represents a serious stress for the body that can trigger long-term metabolic changes. Surgical correction of gastroenterological diseases certainly solves acute problems but in the long term can contribute to the development of metabolic disorders 7 .
These changes can manifest several months or even years after surgery, making it difficult to establish cause-effect relationships.
In women, these processes often coincide with age-related hormonal changes, worsening the situation.
After resections and reconstructive surgeries, absorption of fats, carbohydrates, vitamins and trace elements may be impaired.
Surgical interventions alter the composition of gut microflora, affecting overall metabolism.
The GI tract is the largest endocrine organ, and surgeries can disrupt production of important appetite and metabolism regulators like GLP-1, ghrelin, PYY.
Surgical trauma and subsequent changes can maintain chronic low-grade inflammation underlying insulin resistance.
Metabolic syndrome has acquired the character of a global epidemic. According to research, approximately 35% of the adult US population and up to 46% of patients preparing for surgical interventions meet the criteria for metabolic syndrome 7 . In Russia, the prevalence of this condition also reaches one third of the adult population, with some regional variations 1 .

When metabolic syndrome is suspected in women in the long term after gastroenterological surgeries, the following basic laboratory parameters should be assessed 8 :
Modern research identifies a number of new laboratory parameters that may have prognostic value for early detection of metabolic disorders 1 4 :
| Marker | Direction of Change in MS | Clinical Significance |
|---|---|---|
| HDL | Decrease | Antiatherogenic lipid fraction |
| Triglycerides | Increase | Main source of free fatty acids |
| Insulin | Increase | Manifestation of insulin resistance |
| Fasting Glucose | Increase | Impaired glucose tolerance |
| Leptin | Increase | Marker of leptin resistance |
| Adiponectin | Decrease | Reduced insulin sensitivity |
| hsCRP | Increase | Marker of systemic inflammation |
| Uric Acid | Increase | Association with insulin resistance |

The female body has specific metabolic features that must be considered when assessing metabolic syndrome markers:
Throughout the menstrual cycle, during pregnancy and in perimenopause can affect lipid spectrum and carbohydrate metabolism parameters.
For women differ in some parameters, particularly in waist circumference and HDL levels.
Decreased estrogen levels associated with redistribution of adipose tissue to abdominal type and increased insulin resistance.
To better understand the relationship between GI surgeries and long-term metabolic disorders, a prospective cohort study was conducted involving 120 women aged 35-60 years who underwent various gastroenterological surgeries (gastric resection, cholecystectomy, small and large intestine surgeries) 2-5 years ago. The control group consisted of 60 women of comparable age without history of GI surgeries.
All participants underwent comprehensive examination, including:
The study results revealed statistically significant differences between the group of women after GI surgeries and the control group in most studied parameters.
| Parameter | Main Group (n=120) | Control Group (n=60) | p-value |
|---|---|---|---|
| WC (cm) | 92.3 ± 8.7 | 84.1 ± 7.2 | <0.001 |
| BMI (kg/m²) | 29.8 ± 4.2 | 26.3 ± 3.8 | <0.001 |
| Systolic BP (mmHg) | 134.5 ± 12.3 | 124.8 ± 10.6 | <0.001 |
| Fasting Glucose (mmol/L) | 6.2 ± 0.8 | 5.4 ± 0.6 | <0.001 |
| Fasting Insulin (μU/mL) | 15.8 ± 4.3 | 10.2 ± 3.1 | <0.001 |
| HOMA-IR | 4.4 ± 1.3 | 2.4 ± 0.8 | <0.001 |
| Triglycerides (mmol/L) | 1.9 ± 0.5 | 1.3 ± 0.4 | <0.001 |
| HDL Cholesterol (mmol/L) | 1.1 ± 0.3 | 1.4 ± 0.3 | <0.001 |
| Adiponectin (μg/mL) | 7.2 ± 2.1 | 10.5 ± 2.8 | <0.001 |
| hsCRP (mg/L) | 3.8 ± 1.5 | 1.9 ± 0.9 | <0.001 |

Interestingly, the type of surgery also influenced the severity of metabolic disorders. The most unfavorable profile was observed in women after gastric resection and extensive small intestine resections, likely associated with more significant changes in digestive anatomy and physiology.
For women who have undergone gastrointestinal tract surgery, regular preventive examinations and monitoring of metabolic parameters are especially important. Experts recommend:
Lifestyle correction remains the cornerstone of prevention for metabolic syndrome:
Mediterranean diet with high content of vegetables, fruits, whole grains, fish and limitation of saturated fats and simple carbohydrates is recommended.
At least 150 minutes of moderate aerobic exercise per week. Physical activity increases insulin sensitivity and promotes normalization of lipid profile.
Even moderate weight loss (5-7%) significantly reduces the risk of developing metabolic syndrome and type 2 diabetes 5 .
Considering the features of female metabolism and specifics of surgeries, the approach to prevention and treatment of metabolic disorders should be strictly individual. It's necessary to consider:
Metabolic syndrome in women in the long term after surgical correction of gastroenterological diseases represents a serious interdisciplinary problem requiring attention from both gastroenterologists and surgeons, as well as endocrinologists, cardiologists and therapists.
Modern diagnosis of this condition should include not only assessment of classical criteria, but also determination of new promising markers, such as adiponectin, leptin and inflammation markers, which allow detection of disorders at earlier stages.
Prevention of metabolic syndrome should begin as early as possible—ideally even before planning surgery, and continue throughout subsequent life. Regular monitoring, healthy lifestyle and individual approach are the three pillars on which successful prevention of these serious disorders is based.
Awareness of potential risks and active participation of women in monitoring their health is the most important success factor in preventing long-term metabolic consequences of gastroenterological surgeries.
