Gastrointestinal Issues After Rapid Weight Loss: A Patient's Journey - Surgery

Gastrointestinal issues


Since the end of last year, I lost 26 kilograms through two months of fasting (from a normal weight to significantly underweight).
After that, I binge-eated for a week and gained back 10 kilograms.
Since then, I have been experiencing bloating issues, with a feeling of tightness in my right abdomen.
Previously, I also had a burning sensation.
Every morning, I feel like my intestines near the right side are blocked.
I have undergone colonoscopy, gastroscopy, and CT scans, but no cause was found.
An X-ray showed intestinal gas, sometimes in the stomach, but mostly in the small and large intestines.
I consulted with an internist and took medications to promote motility, including Prucalopride, Gas-X, and magnesium oxide, and I have also tried probiotics, but nothing has improved.
I would like to ask the doctor; one physician suggested that there might be localized intestinal adhesions and recommended laparoscopic exploration.
Is there a chance this could lead to improvement?

Hello Mr.
Chang, if you have not undergone any abdominal surgery, the likelihood of adhesions causing impaired intestinal motility is low (though not impossible).
You mentioned that gas sometimes feels like it's in your stomach and sometimes in the small and large intestines, which suggests that the gas is not confined to the right side of your abdomen.
I recommend having a series of imaging studies reviewed by the same physician for comparison.
If adhesions are still suspected, consider undergoing a laparoscopic surgery for further evaluation.
In the meantime, it may be helpful to assess whether you are experiencing symptoms such as high stress, insomnia, or anxiety, as some patients develop gastrointestinal symptoms due to emotional issues.
Adjusting medication through a psychosomatic approach may help alleviate gastrointestinal symptoms.

Your experience with gastrointestinal issues following significant weight loss and subsequent weight gain is quite complex and warrants a thorough understanding of the underlying mechanisms involved. Rapid weight loss, especially through methods like fasting, can lead to various gastrointestinal symptoms, including bloating, discomfort, and altered bowel habits.
Firstly, it's important to recognize that significant weight fluctuations can impact your gastrointestinal system. When you lost 26 kilograms in two months, your body underwent considerable metabolic changes. Rapid weight loss can lead to alterations in gut motility, changes in gut microbiota, and even affect the secretion of digestive enzymes. This can result in symptoms such as bloating, gas, and abdominal discomfort, particularly if the diet during the weight loss phase was not well-balanced or lacked essential nutrients.

The sensation of pressure or a "stuck" feeling in the right abdomen could be attributed to several factors. One possibility is that the rapid changes in diet and weight may have led to functional gastrointestinal disorders, such as irritable bowel syndrome (IBS), which can manifest as bloating, gas, and discomfort. Additionally, the presence of gas in the intestines, as noted in your X-ray, can contribute to these sensations.

The burning sensation you experienced may indicate acid reflux or gastritis, which can be exacerbated by dietary changes or stress. It's also worth noting that after a period of fasting, the reintroduction of food, especially if it was done excessively or with high-fat or high-sugar items, can lead to gastrointestinal distress.

Regarding the diagnostic tests you've undergone, such as endoscopy and CT scans, it's reassuring that no significant structural abnormalities were found. However, the suspicion of adhesions (scar tissue) causing localized bowel obstruction is a valid concern, especially if you have a history of abdominal surgeries or conditions that could lead to adhesions. Laparoscopic exploration can be a useful diagnostic tool in such cases, and if adhesions are found, they can often be treated during the same procedure.

In terms of treatment, it is essential to continue working closely with your healthcare provider. Since you have already tried various medications to promote motility and manage symptoms, it may be beneficial to consider a multidisciplinary approach. This could include working with a gastroenterologist, a dietitian, and possibly a psychologist or counselor to address any underlying anxiety or stress that may be contributing to your symptoms.

Dietary modifications can also play a crucial role in managing your symptoms. A diet high in fiber, adequate hydration, and smaller, more frequent meals may help alleviate bloating and discomfort. Additionally, keeping a food diary to track what you eat and how it affects your symptoms can provide valuable insights.

Lastly, if you are considering laparoscopic surgery for adhesions, it's important to weigh the potential benefits against the risks. While many patients experience relief from symptoms after such procedures, outcomes can vary, and it's essential to have realistic expectations.

In summary, your gastrointestinal issues following rapid weight loss and subsequent weight gain are likely multifactorial. Continued collaboration with your healthcare team, dietary adjustments, and possibly further diagnostic evaluations will be key in managing your symptoms and improving your quality of life.
