Persistent bloating after significant weight loss, such as the 26 kg you mentioned, can be a frustrating and uncomfortable experience. While there are many potential causes for bloating, it is essential to consider the various factors that could contribute to your symptoms, especially after a significant dietary change like fasting or weight loss.

Firstly, it's important to understand that bloating can arise from several gastrointestinal issues, including but not limited to food intolerances, changes in gut microbiota, and alterations in gastrointestinal motility. After a period of fasting or significant weight loss, your digestive system may take time to adjust. This adjustment can lead to temporary bloating as your body reacclimates to a regular eating pattern.

One common cause of bloating is food intolerances or sensitivities. For example, lactose intolerance or gluten sensitivity can lead to bloating and discomfort after consuming certain foods. Keeping a food diary to track what you eat and any subsequent bloating can help identify potential triggers. If you suspect a food intolerance, consider consulting with a dietitian who can guide you through an elimination diet to pinpoint specific issues.

Another possibility is that your gut microbiota has changed due to your dietary changes. A diet high in processed foods or low in fiber can negatively impact the diversity and health of your gut bacteria, leading to bloating. Incorporating more fiber-rich foods, such as fruits, vegetables, and whole grains, can help promote a healthier gut microbiome and potentially alleviate bloating.

Additionally, rapid weight loss can sometimes lead to gallbladder issues, particularly if the weight loss is significant and occurs over a short period. The gallbladder plays a crucial role in fat digestion, and if it is not functioning optimally, it can lead to digestive issues, including bloating. If you experience other symptoms, such as pain in the upper right abdomen, it may be worth discussing gallbladder function with your healthcare provider.

Regarding your concern about "游離腎" (which translates to "floating kidney" or nephroptosis), it is generally not a common cause of bloating. Nephroptosis occurs when the kidney drops down into the pelvis when a person stands up, which can lead to pain or discomfort but is not typically associated with bloating. However, if you have other symptoms such as flank pain or changes in urination, it would be prudent to discuss these with your doctor.

If you have already consulted with healthcare professionals and have undergone tests without finding a definitive cause for your bloating, it may be beneficial to seek a second opinion or consult a gastroenterologist. They can provide further evaluation and may recommend additional tests, such as imaging studies or endoscopy, to rule out any underlying conditions.

In summary, persistent bloating after significant weight loss can be attributed to various factors, including dietary changes, food intolerances, alterations in gut microbiota, or gallbladder issues. It is essential to keep track of your diet, consider potential food sensitivities, and consult with healthcare professionals for further evaluation. If your symptoms persist or worsen, don't hesitate to seek additional medical advice.
