Why Bariatric Surgery Has Some Health Risks?
Bariatric surgery is usually followed by some complications simply because of two reasons:1- First of all, after surgical treatment, either the amount of your food intake declines or your body absorbs fewer nutrients. As a result, you might face mineral and vitamin deficiencies and the other challenges followed by it.2- The second reason is that all types of surgery have certain complication rates and bariatric surgery is not an exception.
The Most Common Early Complications of Bariatric Surgery
The truth is that weight loss surgery is not among the high-risk surgeries that are currently performed. According to North Bristol NHS Trust, about 1% of bariatric patients deal with a problem after gastric band surgery. However, everything changes from patient to patient according to their health history and mental circumstances.Because sleeve gastrectomy and gastric bypass are more complicated procedures, the complication risk is about 3%. Also, this number has become lower over time since a lot of research has been done in this field to make bariatric abdominal operations safer and it will continue to decrease in the future as well.Here’s a list of the most common post-surgical risks that may threaten your health right away or just a few days after surgery:
- Anastomotic leak is one of the most common complications that will mostly occur till 3 days after the gastrointestinal surgery.
- Bariatric procedures surgeons should watch patients after the surgery and check their heartbeat from time to time. Rapid heart rate, over 120 bpm, fever, and any abdominal pain are worrisome signs of leaks.
- If diagnosed early and treated in the very beginning, there is almost nothing to worry about.
- Unfortunately, bleeding is one of the most common postoperative complications and is seen in up to 11% of gastric sleeve and gastric bypass procedures.
- But fortunately, in 85% of these cases, it is possible to stop the bleeding without surgical operations.
- There are numerous non-operative methods that will help surgeons control and manage bleeding, hemodynamic monitoring, serial hematocrit, and blood product transfusions, to name a few.
- If your surgeon fails to manage bleeding through non-surgical ways, you’ll need emergency surgical management.
3- Bowel Obstruction
- Small bowel obstruction or SBO mostly occurs after gastric bypass surgery.
- It mostly occurs because of an internal hernia.
- Its possibility varies from 0 to 5%.
4- Pulmonary Artery Embolism
- Pulmonary embolism or PE is one of the most common complications, especially after gastric bypass.
- Increased age and higher body mass index (BMI) escalate its possibility.
- The risk of this complication exists until weeks after the surgery. So, PE prophylaxis – a treatment plan for preventing pulmonary embolism – is necessary during this period.
Here’s a demonstration of the chances of each of these early complications.
The Most Common Late Complications of Bariatric Surgery
Any complications that occur after 30 days of your surgery are considered in the long-term or late ones.
1- Dumping Syndrome
Dumping syndrome is one of the most common drawbacks of weight loss surgery. It is caused because consumed food does not undergo complete digestion and is dumped into the large intestine.
2- Internal Hernia
– There is a higher chance of incisional hernias after open gastric bypass, about 20%.- The majority of cases with internal hernias happened between 6 and 24 months after the operation.
3- Low Blood Sugar
– Hypoglycemia is a condition when excess insulin is produced in patients’ bodies, which leads to a quick reduction of glucose.- It occurs because due to the metabolic changes caused by stomach surgery.- During your follow-up sessions, ask your doctor for blood sugar control.4- MalnutritionIt is a part of your surgeon’s responsibility to warn you about the possibility of malnutrition after surgery. This issue occurs mainly because of some changes in absorption of vitamins and absorption of calories overall. It is observed in two types:- Protein-energy malnutrition- Lack of micronutrients such as iron, vitamin B, Vitamin A, folate, and etc.
– Ulcers may occur within weeks or years after the surgery.
6- Acid Reflux
– Acid reflux usually occurs after gastric sleeve surgery or any other type of restrictive surgery when the size of the stomach is decreased.- The reduction of the stomach causes pressure in the stomach, which leads to weakening in the lower esophageal sphincter.
Severe Obesity Surgery Risks by Types
