Diabetes Successfully Treated Using Ultrasound In Preclinical Study (newatlas.com) 63

Posted by BeauHD from the promising-findings dept.
Across three different animal models researchers have demonstrated how short bursts of ultrasound targeted at specific clusters of nerves in the liver can effectively lower insulin and glucose levels. New Atlas reports: Reporting in the journal Nature Biomedical Engineering, a team led by GE Research, including investigators from the Yale School of Medicine, UCLA, and the Feinstein Institutes for Medical Research, demonstrated a unique non-invasive ultrasound method designed to stimulate specific sensory nerves in the liver. The technology is called peripheral focused ultrasound stimulation (pFUS) and it allows highly targeted ultrasound pulses to be directed at specific tissue containing nerve endings. "We used this technique to explore stimulation of an area of the liver called the porta hepatis," the researchers explained in a Nature briefing. "This region contains the hepatoportal nerve plexus, which communicates information on glucose and nutrient status to the brain but has been difficult to study as its nerve structures are too small to separately stimulate with implanted electrodes."

The newly published study indicates short targeted bursts of pFUS at this area of the liver successfully reversed the onset of hyperglycaemia. The treatment was found to be effective in three separate animal models of diabetes: mice, rats and pigs. [...] The study found just three minutes of focused ultrasound each day was enough to maintain normal blood glucose levels in the diabetic animals. Studies in humans are currently underway to work out whether this method translates from animal studies. But there are other hurdles facing broad clinical deployment of the technique beyond simply proving it works. Current ultrasound tools used to perform this kind of pFUS technique require trained technicians. The researchers suggest the technology exists to simplify and automate these systems in a way that could be used by patients at home, but it will need to be developed before this treatment can be widely deployed.

    Not saying this is the solution for all diabetes type 2 cases but there is intermittent fasting... that gives the body time to get rid of insulin between meals and at some point help the liver recover too.

        Frankly I've never felt healthier than these days and my diet, when it isn't shot to hell due to stress eating, consists of one or two meals a day with water in between (a pinch of milk in my earl grey tea at the most), not too much carbs and a good amount of veggies, cooked, greasy as all hell with animal fats. I don't do plant based fats anymore with the exception of coconut, palm or olive.

        I do not know if this is an indicator, but since switching cooking oils, we are able to get our vent clean again. I don't know... I don't trust sunflower, rape seed and co. anymore.

          • You don't just "get" heart problems like this. You are likely hiding your high cholesterol caused by eating a keto diet for so long. Too bad they don't tell you this early on. Saturated fat in diet causes high cholesterol in your blood. It is nearly impossible to eat zero saturated fat if you're on keto. (Assuming you're not only eating avocados.)

            • More recent science strongly suggests that high blood cholesterol is caused by metabolic syndrome, not cholesterol intake. It may be a little more complex in that cholesterol intake was also at one point associated with metabolic syndrome, but a causative relationship was never established in that direction (as best I know).

              So while I don't really like nor recommend animal fats, tropical oils, etc., (and in my personal case can't digest them anyway), my general thought is that people with high blood choles

So I started filtering my espresso through a paper filter and my levels are almost back to normal. My blood pressure too.

    • Type 1 means they need insulin. Many, even most, cases of Type 1 are caused by an auto-immune problem that destroys insulin producing cells, but removing the pancreas for cancer treatment and cystic fibrosis that interferes with many organs can cause it as well.

      Type 1 is a description of necessary treatment, not the cause of the disease.

    • Intermittent fasting has a lot of good science behind it, but it is VERY difficult for most people.

      A potential alternative would be to go for high nutrient-to-calorie ratio foods such as salads, greens, beans, mushrooms, seeds, etc., and preferentially to eat a large amount of those at the start of each meal, and before eating anything higher in calories. You'd get full faster and stay full longer, while eating less calories overall. Dr. Joel Furhman and a number of other nutritional medicine practitioner
