One week of supervised fasting was temporarily reshaped the microbicide of people with type 1 diabetes, making it look like healthy people and improving cholesterol and weight without causing dangerous side effects.

Type 1 diabetes (T1D) is a chronic disease that affects nine million people worldwide. It is noted by a deficiency of hormone insulin reduction of glucose, produced in pancreatic beta cells. A new report to Borders in endocrinology Try the role of prolonged therapeutic fasting as a complementary treatment for T1D.
Import
The T1D is managed by lifelong insulin treatment to replace beta-cell function, combined with careful nutritional management. These patients are at high risk for many other medical conditions, including cardiovascular disease.
T1D is a complex disease with underlying genetic and environmental factors. It has become more common in Western societies over the last three decades, indicating the enhanced role of environmental factors in its causal relevance. In these patients, the gut germalide shows differences in synthesis and function compared to healthy witnesses, both before and after the onset of the disease.
In addition to increased bowel permeability in T1D, these differences could be due to common risk factors for autoimmune diseases (such as T1D) and bowel dysposis. These include the way of birth, nutrition, infections, antibiotic exposure and spiritual stress.
All of these factors cause the loss of beneficial gut bacteria and their metabolites. For example, metabolites such as short-chain fatty acids (SCFA) and immunomodulatory metabolites contribute to bowel health while maintaining the balance of the regulatory T cells and pre-inflammatory cells TH17. They also maintain the integrity of the epithelial barrier of the bowel, maintaining toxins and pathogens from the body and blood.
Such negative interactions in early life can predispose colonization from pathogens, leading to intestinal inflammation. Other bowel germs can cause autoimmunity, expressing antigenic positions that are very similar to self-antigine, known as “molecular imitation”. For example, Parabacteroides Distasonis It contains a sequence similar to a significant on -site insulin. Its presence is associated with higher T1D growth rates in mice and children.
In addition to insulin, T1D management approaches focus on slowing down the destruction of beta cells with immunomodulators and biologically. These are expensive, with significant side effects, and are required for lifelong, such as insulin.
Therapeutic fasting is a nutritional approach that improves the symptoms of multiple autoimmune diseases and changes the microbial intestine profile into healthy individuals. The question in this study was whether these changes also occur in patients with T1D. Fasting studies, including the monthly Ramadan observed rapidly by Muslims or seven -day supervisor, have shown their safety in selected patients with at least T1D. The restriction of metabolic fuel can quickly weaken the autoimmune response, lend biological credibility to this case.
In mice models, recurring fasting cycles reduce the risk of autoimmunity and enhance the regeneration of beta cells and the proliferation of Treg. Fasting also affects the gut microbicide in mouse studies. For example, it leads to the production of β-hydroxybutyry, a significant fuel molecule during fasting. This is exhausted BacterialReduction of intestinal activity TH17.
Many species experience displacements related to fasting in abundance. It is likely that the restriction of nutrients promotes the propagation of germs of the intestinal by a more different metabolic portfolio, allowing them to go to nutrients from the host.
Study findings
The current pilot study included 19 patients with T1D and ten tests, mainly females. The average body mass index (BMI) was 27.7 kg/m2 and 26.2 kg/m2, respectively.
Prolonged fasting periods have strongly changed the structure and composition of the gut’s bowel in patients with T1D, leveling it to witnesses. Immediately after the end of the fasting period, the gut germalide is very similar to that of non -diabetic controls, but no long -term displacement was created. Diabetic ketoacidosis did not happen with fasting on the T1D group.
Fairly associated with fiber Lachnospiraceae declined while mucin/glycosaminoglycane degrade Lachnospiraceae and some Tacitals increased during fasting. These are one of the largest producers of the butyerian SCFA, who thrive on a fiber -rich diet and usually break down fiber. As a result, these members may not thrive in periods with a shortage of fiber, such as during fasting periods.
The fasting shape in this study included ~ 200 kcal/day of juices and broth, which provided very few dietary fibers. This could help explain why TAXA fiber adapted were reduced while TAXAs that degrade mucin were developed.
However, not all members of these families change in the same way. Other taxolines that dismiss mucinin and glucosaminoglycans increase in fasting response, as mentioned in different studies. This shows a displacement to the use of sources of energy derived from the host, including β-hydroxybUTy.
These taxonomic changes were associated with changes related to fasting in blood pressure and cholesterol levels. Both BMI and the reason for bad to good cholesterol (low density lipoprotein, LDL and high density lipoprotein, HDL, respectively) improved during the fasting and monitoring period. This change was similar to that previously mentioned in non -diabetic patients.
In the checks, the post-widespread standards reflect these on the T1D, but they did not reach statistical significance, probably due to the small size of the sample.
Compared to a small group of ten patients with multiple sclerosis in repeated prolonged fasting, many areas of the microbial intestine have shown overlays, as did groups without autoimmune.
This suggests that the results of fasting in the microbicide are independent of host health and the type of disease, although larger studies are needed to confirm this. The gut microbiocide responds to fasting in a preserved way, probably because bowel germs are forced to use different metabolic routes to use host nutrients.
While taxes that collapse nutrition sources reduce abundance during fasting, those that can turn to the use of other energy substrates thrive. “This suggests that, next to the use of β-hydroxybutyry for their own diet, the microbial intestine could play an important role in increasing ketone ketone production during periods fasting. ”
The specific taxonomics that are increasing during fasting can cause immunological tolerance for environmental stimuli, perhaps contributing to reduced inflammation with fasting.
Conclusions
The findings of this study show that “Fasting under medical supervision is safe and may prove to be beneficial to patients with T1D. “The results suggest that the gut microbicide is shaped by the availability of nutrients and not by the presence of disease.
Clinical results associated with the need to investigate the causal links between the changes of guts of the bowel and the reported clinical improvements to fasting. More research is needed to understand the long -term value of fasting as a complementary treatment in these patients. In addition, the speed at which the microbial rehabilitation should be explored during the reform should also be explored.
