Kelly isn’t sure why the woman gained weight, but animal studies have suggested that gut bacteria may play an important role in how the body processes and stores calories.
That’s one reason that the folks at OpenBiome -- the place that’s making those new FDA-approved, capsules of freeze-dried stool -- are extremely picky about their poop. Donors must pass a rigorous screening process. Only 3% of applicants are accepted, says James Burgess, the company’s executive director and co-founder.
Burgess says they exclude candidates at different stages of the screening process. Often it’s because a potential donor harbors a germ in their stool they didn’t even know they had.

NSAIDs Injure Gut Lining and Mitochondria
Many individuals use aspirin, ibuprofen, Motrin, or other NSAIDs without a second thought. Daily aspirin intake is oftentimes recommended by physicians to reduce stroke and heart attack risk. Potential side effects may briefly be explained to the patient, but it’s unlikely the full scope of injury is understood. NSAIDs have significant side effects that affect the digestive tract in addition to other parts of the body. In an attempt to buffer the side effects, proton pump inhibitors (PPIs) or acid blocking drugs are often prescribed with the NSAIDs. Science shows us the dark-side of these medications. NSAIDs are deemed as safe, however acute critical and chronic subtle adverse effects impact the body. In this article, I will focus on the chronic gut effects and mitochondrial damage that may be affecting you and how you can keep your gut healthy.
NSAIDs
NSAIDs (non-steroidal anti-inflammatory drugs) are some of the most commonly used pain-relieving drugs in the world. NSAIDs block pain, lower fever, and reduce swelling. They accomplish this by blocking the enzymes Cox-1 and Cox-2 which make prostaglandins that lead to pain, swelling, and inflammation. NSAIDs are available over-the-counter and by prescription and include aspirin (Bufferin, Bayer, Excedrin), ibuprofen (Advil, Motril, Nuprin) ketoprofen (Actron, Orudis), naproxen (Aleve), Celebrex, Daypro, Indocin, Lodine, Naprosyn, Relafen, Vimovo, and Voltaren.
FDA Cautions
The FDA provides these recommendations on NSAIDs use. NSAIDs should only be used exactly as prescribed, at the lowest dose possible for treatment, and for the shortest time needed. There are a number of concerns with NSAIDS like increased risk of heart attack and stroke, and increased risk of an ulcer or GI bleed. FDA guidelines show increased risk with:
• Past history of stomach ulcers, or stomach or intestinal bleeding with use of NSAIDs
• Taking medicines called corticosteroids, anticoagulants, SSRIs or SNRIs (antidepressants)
• Increasing doses of NSAIDS
• Smoking
• Drinking alcohol
• Older age (65 and older)
• Poor health
• Advanced liver disease
• Bleeding problems
Side Effects of NSAIDs: An Expanding Trail of Side Effects in the Digestive Tract
Ulcers and Erosions
Ulcers and stomach damage occur from NSAIDs because of their effects on the Cox enzymes. Many NSAIDs are prostaglandin and cox-enzyme inhibitors which blocks pain and swelling. But these same compounds are needed in the digestive tract for defense in the small intestine.
Scientists have figured out that when prostaglandins are blocked, then ulcers and GI bleeds occur, protein loss, strictures develop, and even perforations of the gut occur.
Small Intestine Injured with NSAIDs
NSAIDs adverse effects impact more than just the stomach and stomach ulcers. Over 20 years ago, it was recognized that NSAIDs “have profound effects on the small intestine”. A study published February 1996 reported that “NSAIDs cause quite distinct and severe biochemical damage during drug absorption (uncoupling of mitochondrial oxidative phosphorylation proving to be most important) which results in increased intestinal permeability.” It was felt at the time that aspirin was not associated with changes in gut permeability. It was also noted that long-term use of NSAIDs required months of repair and recovery as the tissues did not quickly bounce back.
Contrary to the 1996 report, human studies in 2015 show that aspirin does lead to increased intestinal permeability effect and is “similar to other NSAIDS but of lesser magnitude.”
NSAID Enteropathy
In 1999, a study noted that poor diagnostic tools were problematic for evaluating NSAIDs effect on the small intestine. However, it was noted that NSAIDs use created a low-grade “NSAID-enteropathy”. This was a term introduced to describe the damaging effects of NSAIDs on the intestinal tract. NSAIDs enteropathy is described as a syndrome linked with increased intestinal permeability (leaky gut syndrome), low-grade inflammation, blood loss (iron deficiency anemia) and protein loss (low albumin levels).
NSAIDs drug-induced small intestine damage occurs in a single layer of cells known as the intestinal epithelium. The intestinal epithelium is a single layer of cells lining the inside of the gut that provides critical protection and homeostasis to the gut and immune system. The epithelial layer acts as a barrier and coordinates between the gut bacteria and immune cells. (This has some similarities to the endothelium in blood vessels that gets injured in heart disease.)
NSAIDS injure this delicate epithelial layer as it causes erosions or sloughing off of the lining and leads to perforations and ulcers within the small intestine. NSAIDs also adversely affect phospholipids, which are necessary fats for cell membranes within the epithelial lining which help keep the intestinal mucus barrier intact.
NSAIDS Damage Gut Mitochondria
Mitochondrial damage is another dark-side of NSAID-induced injury. NSAIDs, including aspirin, damage mitochondria as it leads to uncoupling or a breakdown of oxidative phosphorylation, the process used by mitochondria to make energy or ATP. Mitochondria are little organelles found in virtually all our cells. They produce chemical energy or ATP in the process of burning up food via oxidative phosphorylation which requires oxygen.
Mitochondrial do other things too like break down and recycle waste products to help reduce toxicity and conserve energy. Damage to the oxidative phosphorylation process results in increased levels of toxic reactive oxygen species (ROS) or free radicals. Failure of the electron transport chain occurs and leads to suppressed ATP production or loss of energy and induces cell death. Think about this - NSAIDs are designed to help manage inflammation, but the reality is they create another inflammatory mess, i.e. NSAIDs-enteropathy.
Gut Injury More Prevalent
NSAIDs side effects not only run deeper than previously understood, but the number of individuals affected by adverse drug-effects is much higher than thought. In fact, some studies show since the advent of the pill cam used in GI testing an estimated 40-90% of NSAID users had injury to their small intestine seen as erosion or ulcer that could lead to bleeding, perforation, or other types of damage to the gut.
Mitochondrial stress will not be seen on any imaging study. Rather it will be felt in a variety of ways. Learn more about mitochondria injury in the article Mitochondria – Drugs that Injure and What Mitochondria Injury Looks Like. When your physician ordered you to take aspirin or other NSAIDs every day, did they warn you about any of these concerns?
Acid Blockers Worsen NSAIDs Damage
Proton-pump inhibitors (PPIs) or acid blocking drugs are often prescribed along with NSAIDs. The intention is that these acid blocking drugs will protect the stomach and duodenum, the first part of the small intestine from NSAIDs drug injury. Evidence says otherwise. A 2014 study concluded “it is becoming clear that suppression of gastric acid secretion significantly worsens NSAID-enteropathy”.
Similar to previous findings, the Journal Pharmacological Toxicological Methods March-April 2016 proved that the use of NSAIDs with PPIs alone or together caused negative changes in both the stomach and small bowel. In an animal model that simulated common human clinical experience, scientists found the presence of multiple erosive lesions or ulcers present in the stomach and small intestine in animals treated with NSAIDs and PPIs.
Additional findings showed lab values consistent with poor digestion, malabsorption, anemia, decreased hemoglobin, hematocrit, serum albumin, and serum total protein levels. Increased intestinal gut permeability or leaky gut syndrome was also found with both NSAIDs and PPIs use. The conclusion of the article – “this paper provides yet another evidence for PPI induced exacerbation of NSAID enteropathy.” The walking wounded get sicker.
Stress Worsens NSAIDs Damage to Gut
If these meds aren’t enough to rip holes in your gut and damage
e bacteria were found in the small intestine as well as increased intestinal permeability. (Increased bacteria in the gut is known as SIBO/small intestinal bacteria overgrowth). Given the amounts of ongoing chronic stress and concomitant use of NSAIDs, this certainly adds to the conundrum.
