![]() IBS Diet, Irritable Bowel Syndrome Diet & IBS Recipes An estimated 15-20% of all Americans have Irritable Bowel Syndrome, or IBS, and it's a devastating, incurable. A Johns Hopkins expert explains how what’s going on in your gut could be affecting your brain. Irritable bowel syndrome (IBS) is a gastrointestinal disorder that affects approximately 11 percent of the worldwide population. More women tend to be afflicted with. Irritable bowel syndrome (IBS) is common in the general population and has a significant medical and socioeconomic impact. Its pathophysiology is still not entirely. Humans have been eating fermented foods since the time of the Paleolithic, but modern research suggests they may be good for your brain as well as your gut. ![]() By taking these steps and seeking out the underlying causes of IBS, you can dramatically improve your health and overcome your digestive disorder.

Irritable Bowel Syndrome - Symptoms, Treatment, and More. Irritable bowel syndrome (IBS) is a health problem that many people have but few people talk about. People who are diagnosed with IBS experience chronic symptoms related to the workings of their intestines. What Is IBS? IBS is a digestive disorder in which people experience recurrent bouts of abdominal pain, alongside significant changes to their experience of bowel movements. People who have IBS may experience chronic constipation, episodes of urgent diarrhea, or flip- flop back and forth between the two extremes. Click to see IBS potential triggers and symptoms. IBS is classified as a functional gastrointestinal disorder, in that it involves a malfunction in how the intestinal system works, but doesn’t present with any signs of visible disease process or tissue damage. It is estimated to affect up to 1. IBS symptoms may vary from person to person, or may vary over time for each individual who has the disorder. People who have IBS may experience: Abdominal pain, cramping, spasms, or discomfort (often relieved by a bowel movement)Diarrhea: loose, watery stools, possibly with feelings of urgency, and/or three or more bowel movements a day. Constipation: hard, dry stools, straining on the toilet, and/or three or fewer bowel movements a week. Feelings of incomplete evacuation after a bowel movement. Excessive intestinal gas. Bloating, which often worsens as the day goes on. Changes to the look of stools. Mucus on stools. Top 4 Things to Know About IBSResearchers are not yet quite clear why people develop IBS. Often the disorder manifests itself following a severe bout of gastroenteritis, otherwise known as the stomach flu. Sometimes symptoms appear after the experience of an extremely stressful event. A high incidence of IBS is seen in adults who were the victim of sexual or physical abuse in childhood. IBS is diagnosed based on symptoms, as opposed to test results. This is because signs of IBS do not show up on diagnostic tests. Your doctor may choose to run some tests, based on your clinical picture and medical history, but these tests are used to rule out other digestive diseases that may be causing your symptoms. The lack of positive test results does not mean that IBS is all in your head. Research indicates that IBS symptoms may be the effect of an interaction among many factors, including some or all of the following: Changes in gut motility - the speed of intestinal movement. Visceral hypersensitivity - higher feelings of pain in internal organs than normal. Inflammation in the lining of the intestines. Dysfunction in the communication systems between the gut and the brain. An imbalance among gut bacteria. Food intolerance or sensitivity. Increased intestinal permeability (leaky gut syndrome)IBS can be broken down into different sub- types: diarrhea- predominant (IBS- D), constipation- predominant (IBS- C), and alternating type (IBS- A), in which the predominant bowel symptom changes over time. What Else Could It Be? IBS is diagnosed after other disorders have been ruled out through routine diagnostic testing. The following are some of the health conditions that your doctor will want to rule out: Celiac Disease: Celiac disease is a condition in which eating foods that contain gluten results in a problematic autoimmune response in which the villi lining the small intestine are damaged. People who have IBS are at higher risk for undiagnosed celiac disease. Inflammatory Bowel Disease (IBD): The inflammatory bowel diseases of Crohn’s disease and ulcerative colitis present with many of the same symptoms as IBS. However, IBD symptoms include bloody diarrhea, weight loss, and fevers, all symptoms that are not present in IBS. In addition, with IBD, visible signs of inflammation will be seen in the digestive tract during a colonoscopy. Food Intolerance: A food intolerance differs from a food allergy in that the problem occurs at the level of the digestive system as opposed to an immune system response. Food malabsorption or intolerance can cause IBS- like symptoms. Two of the more common kinds are lactose intolerance and fructose malabsorption. Colon Cancer: People who have IBS frequently worry that they might have colon cancer that has been missed by their doctor. Symptoms of colon cancer that are not seen in IBS are signs of rectal bleeding or bloody stools, anemia, extreme fatigue, and significant unexplained weight loss. If You Have Recently Been Diagnosed With IBSAlthough your doctor may tell you that there is no cure for IBS, you may find reassurance in the fact that there are plenty of things that can be done to help to quiet your symptoms. Here are some things for you to learn more about: Medication options: Your doctor may choose to prescribe you a medication designed to ease your symptoms. Available options include: Antispasmodics: May be prescribed for relief of abdominal pain and cramping. Antidepressants: May be prescribed for pain reduction and to address any co- existing depression or anxiety symptoms. Antibiotics: Specific types may be prescribed that target a possible overgrowth of bacteria in the small intestine (SIBO)IBS- specific medications: These include Amitiza and Linzess for IBS- C and Viberzi for IBS- D. Over- the- Counter Remedies (OTCS): Talk to your doctor about what OTCs are safe for you to use. OTCS that are more commonly used by people who have IBS include laxatives, probiotics, peppermint oil, antidiarrheal agents, and certain herbal supplements. What to Eat! Figuring out what foods to eat when you have IBS can be challenging. It can be helpful to keep a food diary to look for any possible connection between the foods that you eat and the symptoms you are experiencing. The low- FODMAP diet has strong research support for its effectiveness in reducing IBS symptoms, but can be challenging to follow. Increasing dietary fiber, particularly soluble fiber, can be helpful if done slowly. In addition to learning what foods are best for you to eat, you should also pay attention to how you eat. You may find it to be helpful to eat smaller meals as large, heavy meals can strengthen intestinal contractions. A Word From Verywell. Although we have all learned to keep . Talk openly with your doctor about your symptoms, so you can come up with an optimal treatment plan. Seek out IBS support groups online so that you will not feel like you are all alone in dealing with this frustrating health problem. Taking a matter- of- fact approach to your IBS will help to lower your stress level and serve to protect your self- esteem. Sources: Minocha A.

Our Second Brain. If you’ve ever had your stomach in knots before speaking in public, then you know the stomach listens carefully to the brain. In fact, according to William Whitehead, Ph. D, a professor of medicine and an adjunct professor of psychology at the University of North Carolina, the entire digestive system is closely attuned to a person’s emotions and state of mind. People with irritable bowel syndrome often suffer symptoms during times of stress and anxiety, and even perfectly healthy people can have an increase of stomach pain, nausea, constipation or diarrhea during stressful life events. There is a constant exchange of chemicals and electrical messages between the two systems. In fact, many scientists often refer to them as one entity; the brain- gut axis. Therefore, what affects the stomach will directly affect the brain and vice versa. Medications designed to target the brain can also cause nausea, diarrhea, constipation or abdominal upset because the body actually has two brains – one encased in the skull, and a lesser known but vitally important one found in the human gut. Fat- soluble drugs penetrate the gut wall and can injure the natural balance of the digestive system. Antidepressants, benzodiazepines and sleeping pills are all fat- soluble, meaning they dissolve in fat and not water. SSRIs (Selective Serotonin Reuptake Inhibitors) are believed to ease depression by enhancing levels of Serotonin to the brain. But 9. 5% of the Serotonin in the body lies in the digestive system, and diverting the supplies of Serotonin from their natural receptors can increase anxiety, alter sleep patterns, cause sexual dysfunction and adversely affect the cardiovascular region. Balancing the hotbed of Serotonin production in the gut is critical to restoring the balance. Some scientists believe that SSRIs boost Serotonin in the gut and change the signals to the brain, since antidepressants prevent the uptake of Serotonin by cells that should be using it. But Serotonin is calming to the digestive tract. This may explain why some SSRI users experience nausea, stomach upset, constipation, diarrhea, and fluctuations in appetite. GABA receptors for Benzodiazepines and Sleeping Pills are also located in the gut and depress gastrointestinal movement, which can cause constipation. But the continued use of medications that target GABA also increase the level of stress on the body. And in many ways, the connection between stress and the gut may be the most visible brain- gut connection. This may explain why the gut naturally produces benzodiazepines, to keep the natural state of calm that is necessary for proper functioning. Nearly every chemical that controls the brain is also located in the stomach region, including hormones and neurotransmitters such as Serotonin, Dopamine, Glutamate, GABA and Norepinephrine. The gut contains 1. But there are also two- dozen small brain proteins; major cells of the immune system; one class of the body’s natural opiates; and native benzodiazepines. The gut, known as the enteric nervous system, is located in sheaths of tissue lining the esophagus, stomach, small intestine and colon, and plays a key role in human emotions. But few know the enteric nervous system exists, and therefore gut health is often overlooked. Symptoms from the two brains can get confused, and just as the brain can upset the gut, the gut can also upset the brain. The brain signals the gut region by talking to a small number of command neurons, which in turn signal relay neurons that carry messages and control the pattern of activity in the gut. The term Solar Plexus simply refers to the nerves in the abdomen. But these plexuses also contain cells that nourish neurons and are involved in immune response and the protection of the “blood brain barrier” to keep harmful substances away from the important neurons. There are also sensors for sugar, protein, acid and other factors that monitor the progress of digestion, determining how the gut mixes and handles its contents. During sleep, the head’s brain produces 9. REM) where dreams occur. During the night, when it is empty, the gut’s brain produces 9. These two brains are linked even in sleep. Individuals with bowel problems have been shown to also have abnormal REM sleep. When the central brain encounters severe tension, it releases stress hormones that prepare the body for flight or fight. The stomach in turn contains many sensory nerves that are stimulated by this chemical surge – thus the feeling of butterflies. Fear also causes the Serotonin circuits in the gut to increase their intensity, resulting in diarrhea. Both stimulation and inhibition are important to the normal transmission of messages. GABA neurons selectively slow the excited responses, which is why benzodiazepines are known to dampen experiences. GABA enhancing drugs such as benzodiazepines and sleeping pills perform a sedative force on the GABA receptors. But GABA is meant to only periodically regulate the excited transmissions, and the long- term intensification of GABA can decrease the receptor’s ability to reduce excitation – thus creating increased anxiety, insomnia and depression. Any drugs that alter the balance of these neurotransmitters can also affect sleep. The answer is not to add more GABA, Serotonin or other chemicals, but to restore the equilibrium of chemical production. There is a natural symphony of chemicals in the stomach region that balance our emotions, sleep, pain and energy. Benzodiazepines cause profound alterations throughout the brain and gut and an eventual reduction in GABA levels. Dose tolerance and abrupt withdrawals may be accompanied by uncontrolled release of Dopamine, Serotonin and other neurotransmitters. Lower GABA levels cause an increase in Norepinephrine that encourages quick emotional responses such as anger, and discourages deliberate logical thinking. High Norepinephrine causes adrenalin to be released, which can cause the heart to beat faster and harder. This also causes red corpuscle reserves to be placed in the bloodstream, which in turn causes energy sources, nutrients and oxygen to be diverted from organs and into the muscles. This is where high blood pressure occurs. But low GABA also causes a decrease in Serotonin, which makes sleep difficult and causes depression, irritability and a lack of rational emotion. The benzodiazepine receptors are also involved in the regulation of pain perception, modulation of the immune and inflammatory systems, and the protection of cells from damage by free radicals. This helps to explain why continued use of benzodiazepines can increase pain and cause a breakdown of the immune system, while also inducing anxiety and insomnia. Often a painkiller is added. But pain medication lowers natural Opioid levels, resulting in abnormal pain perception - causing an increase in Dopamine release that leads to anxiety. Continued Dopamine release causes emotional fatigue. Low Opioid levels also cause the lowering of GABA, which can increase anxiety, insecurity, unexplained panic and depression. The Serotonin reduction further decreases Opioid levels, and the Stress Cycle repeats with increasing intensity. Every time one neurotransmitter is altered, it starts a chain reaction in the remaining chemicals. Because many medications stimulate sensory nerves in the stomach, they can also cause nausea, constipation or diarrhea. Even some antibiotics act on gut receptors, causing cramps and nausea. Drugs like morphine and benzodiazepines attach to the gut’s GABA receptors and produce constipation. SSRIs work by redistributing neurotransmitters such as Serotonin and Norepinephrine, which can cause constipation or diarrhea. Therefore, a healthy stomach is essential to keep the precise balance of chemicals for optimal mental and physical health. Various chemicals in the stomach also work to breakdown food. They include the digestive enzymes pepsin, rennin and lipase, but also the production of hydrochloric acid to establish a suitable environment for the enzymes and assist in digestion. Often additional medications are added to stop the production of stomach acid in an attempt to ease gas, bloating and pain. But without adequate acid, the entire sequence of digestion can become compromised, since gastric acid is necessary for optimal digestion and nutrient assimilation. Hydrochloric acid is the prevalent stomach acid that is secreted naturally and is necessary to breakdown and absorb protein; activate enzymes; and for the absorption of carbohydrates, fats, vitamins and minerals. The presence of acid also assists in muscle contractions that push food through the intestines while destroying parasites, bacteria, fungi and other invaders. Without sufficient acid, microorganisms that are normally destroyed can proliferate, raising the risk of gastrointestinal infections. Additionally, the acid coming from the stomach tells the pancreas and gall bladder to pour alkaline juices in the small intestine. Without the alkaline release, a systemic acid level can build to dangerous levels, and has been associated with cardiovascular disease, diabetes and cancer. And of course, an imbalance in the stomach adversely affects the brain, resulting in increased anxiety, depression and insomnia. The digestive tract should have 4. Antibiotics not only kill the harmful bacteria, but also destroy beneficial bacteria essential to a healthy digestive tract. This in turn impairs digestion and the assimilation of nutrients. But stress, medications, poor diet and even treated city water that contain chlorine and sodium fluoride all contribute to the breakdown of the healthy stomach bacteria. Therefore, it is important to replenish the friendly bacteria to promote good gut health. A healthy lower intestine should contain at least 8. E. Our bodies can sustain healthy states with 1. Probiotics are carefully prepared friendly bacteria that replenish the microbial balance.
