In the United States, more than 100 million adults, or approximately 40 percent of the adult population, have obesity and for decades obesity prevalence has steadily climbed. Obesity is a chronic condition that increases the risk of other chronic and life-threatening conditions like hypertension, type 2 diabetes, coronary heart disease, stroke, and certain cancers. People with obesity also experience high rates of weight stigma or stereotyping, mistreatment, and social devaluation related to body weight.

For people with obesity, bariatric surgery may be an option. Bariatric surgery can result in significant weight loss and the improvement, prevention, or resolution of many related diseases including type 2 diabetes, heart disease, hypertension, sleep apnea, and certain cancers. Bariatric surgery has also been shown to produce major reductions in clinical morbidities such as cardiovascular events, and may reduce long-term mortality risk in obese individuals by as much as 40 percent. Over the past 10 years, about two million people living in the U.S. have undergone the two most common types of bariatric surgery, which include sleeve gastrectomy and Roux-en-Y gastric bypass, with more than 200,000 new procedures performed every year. 

In addition to the established clinical benefits of bariatric surgery, the general safety of bariatric surgery is also well-established, with complication rates in line with common surgical procedures such as minimally invasive gallbladder removal. However, in a rare subset of people, a potentially debilitating condition called post-bariatric hypoglycemia may present in the years following bariatric surgery.

Understanding post-bariatric hypoglycemia

Post-bariatric hypoglycemia, or PBH, is a condition that can occur one or more years after undergoing bariatric surgery. While the exact cause of PBH is not fully understood, an excessive GLP-1 response to meals is believed to play a primary role. Excessive GLP-1 levels lead to hypersecretion of insulin, and this high level of insulin causes blood sugar levels to drop too low, a condition called hypoglycemia. 

PBH can cause persistent, recurrent, and debilitating hypoglycemic events for some individuals. Some symptoms, such as sweating, tremors, and palpitations, are caused by the body trying to raise blood sugar levels. Other symptoms occur due to an inadequate supply of blood sugar to the brain. This deprivation can manifest as impaired cognition, loss of consciousness, seizures, and other symptoms that can result in major disruptions to independent living. 

Repeated instances of hypoglycemia can lead to hypoglycemia unawareness, a condition in which the body does not produce the typical early signs and symptoms of low blood sugar. Failure to recognize hypoglycemia early can increase the risk of serious events, further impairing safety and requiring the assistance of others.

Addressing conditions with high unmet need

It is estimated that PBH affects approximately 8 percent, or 160,000, of the two million people in the U.S. who have undergone the two most common types of bariatric surgery in the past decade. 

There are currently no approved therapies for PBH, but the scientific community is making strides in advancing research. Amylyx, a clinical-stage pharmaceutical company based in Cambridge, Massachusetts, is focused on developing potential new therapies for communities with high unmet needs, including for individuals with PBH. 

“We feel an unwavering responsibility to the communities with high unmet need, and taking on such responsibility is at the heart of what we do. Our research is guided by the emerging science and inspired by the understanding that people living with conditions like PBH have been doubted, or even ignored, and living in search of answers for far too long,” said Camille L. Bedrosian, MD, chief medical officer of Amylyx and an expert with nearly 30 years of experience addressing unmet medical needs for people with rare and serious conditions through successful clinical and translational research programs. 

For people living with PBH, each day can feel like a battle against persistent, recurrent, and debilitating hypoglycemic events that have a profound impact on their quality of life, rendering many unable to drive, work, live alone, or care for dependents. Fortunately, the scientific understanding of PBH is advancing rapidly — as are potential therapies in clinical trials — giving hope to people living with PBH and their families.

FEMA pressures staff to rat out colleagues who have criticized Trump anonymously: report



A number of Federal Emergency Management Agency staff that openly criticized President Donald Trump are under intense investigation from FEMA leadership, and under threats of termination should they refuse to reveal the names of their colleagues who criticized Trump anonymously, Bloomberg reported Thursday.

Nearly 200 FEMA employees signed onto a letter in August pushing back against the Trump administration’s cuts to FEMA, warning that the cuts could jeopardize the agency’s ability to adequately respond to disasters.

More than a dozen FEMA employees – all of whom signed onto the letter – were soon placed on leave. Now, remaining staff that had signed onto the letter using their name are being investigated by agency leadership, being threatened to reveal the names of their colleagues who signed the letter anonymously, according to insiders who spoke with Bloomberg and documents reviewed by the outlet.

“The interviews with FEMA workers have been carried out by the agency's division that investigates employee misconduct, and those interviewed have been told they risk being fired for failure to cooperate,” Bloomberg writes in its report. “The employees have been instructed not to bring counsel, according to people familiar with the process.”

The revelation that FEMA staff under investigation were being instructed not to bring legal counsel was revealed, in part, by Colette Delawalla, the founder of the nonprofit organization Stand Up for Science, the same organization that helped FEMA staff publish its letter of dissent.

“They are not really given an option not to comply,” Delawalla told Bloomberg. “They don’t have guidance while they’re in there.”

Trump has previously said he wanted to phase out FEMA and “bring it down to the state level,” with the agency struggling to respond to emergencies such as the deadly Texas flood in July following new Trump administration policies that led to funding lapses for the agency.

A previous batch of FEMA employees – 140 of them – were placed on leave back in July for signing onto a different letter of dissent, which itself followed a number of FEMA employees being forcibly reassigned to work for Immigrations Customs and Enforcement amid Trump’s mass deportation push.

Critics have characterized the FEMA purges as a blatant violation of the Whistleblower Protection Act, which provides clear protections for government employees from retaliation for disclosing information that is a “specific danger to public health or safety.”
