How Does Diabetes Affect The Digestive System?

How Does Diabetes Affect The Digestive System
What Is Gastroparesis? – Normally, your stomach muscles tighten to move food through your digestive tract. If you have gastroparesis, nerve damage from high blood sugar can cause those muscles to slow down or not work at all. Your stomach doesn’t empty properly, and your food may take a long time to leave your stomach.

Does diabetes affect the intestines?

Article Sections – Gastrointestinal complications of diabetes include gastroparesis, intestinal enteropathy (which can cause diarrhea, constipation, and fecal incontinence), and nonalcoholic fatty liver disease. Patients with gastroparesis may present with early satiety, nausea, vomiting, bloating, postprandial fullness, or upper abdominal pain. The diagnosis of diabetic gastroparesis is made when other causes are excluded and postprandial gastric stasis is confirmed by gastric emptying scintigraphy. Whenever possible, patients should discontinue medications that exacerbate gastric dysmotility; control blood glucose levels; increase the liquid content of their diet; eat smaller meals more often; discontinue the use of tobacco products; and reduce the intake of insoluble dietary fiber, foods high in fat, and alcohol. Prokinetic agents (e.g., metoclopramide, erythromycin) may be helpful in controlling symptoms of gastroparesis. Treatment of diabetes-related constipation and diarrhea is aimed at supportive measures and symptom control. Nonalcoholic fatty liver disease is common in persons who are obese and who have diabetes. In persons with diabetes who have elevated hepatic transaminase levels, it is important to search for other causes of liver disease, including hepatitis and hemochromatosis. Gradual weight loss, control of blood glucose levels, and use of medications (e.g., pioglitazone, metformin) may normalize hepatic transaminase levels, but the clinical benefit of aggressively treating nonalcoholic fatty liver disease is unknown. Controlling blood glucose levels is important for managing most gastrointestinal complications. Gastrointestinal (GI) complications of diabetes have become more common as the rate of diabetes has increased. These complications and their symptoms are often caused by abnormal GI motility, which is a consequence of diabetic autonomic neuropathy involving the GI tract. Although some studies have indicated that diabetic autonomic neuropathy is linked to the duration of diabetes, the Diabetes Control and Complications Trial suggested that, at least in persons with type 1 diabetes, neuropathy and other GI complications are associated with poor blood glucose control and not necessarily the duration of diabetes.1 – 3 GI conditions caused by diabetes include gastroparesis, intestinal enteropathy (which can cause diarrhea, constipation, and fecal incontinence), and nonalcoholic fatty liver disease. Esophageal manifestations of diabetic neuropathy, including abnormal peristalsis, spontaneous contractions, and impaired lower esophageal sphincter tone, result in heartburn and dysphagia.4, 5 The relationship between hyperglycemia and dysmotility is not well established. Although many patients may have objective evidence of esophageal dysmotility or reflux, symptoms only occur in a minority of patients with diabetes.6 Other possible factors contributing to diabetes-associated reflux include obesity, hyperglycemia, and decreased secretion of bicarbonate from parotid glands. Treatment consists of controlling blood glucose levels and using medication to manage reflux. Approximately 5 to 12 percent of patients with diabetes report having symptoms consistent with gastroparesis.7 Gastroparesis is more common in women and can present as early satiety, nausea, vomiting, bloating, postprandial fullness, or upper abdominal pain. Delayed gastric emptying contributes to poor blood glucose control and may be the first indication that a patient is developing gastroparesis.4 The delayed gastric emptying in patients with gastroparesis is thought to be caused primarily by impaired vagal control.8 Other contributing factors include the impairment of inhibitory nitric oxide–containing nerves, damage to the interstitial cells of Cajal, and underlying smooth muscle dysfunction.9 A technical review from the American Gastroenterological Association (AGA) recommends performing an initial evaluation consisting of a patient history and physical examination, complete blood count, thyroid-stimulating hormone test, metabolic panel, amylase test (if the patient has abdominal pain), and pregnancy test (if appropriate).10 This should be followed by upper endoscopy or an optional upper GI series with small bowel follow-through to rule out mechanical obstruction or other GI conditions, and ultrasonography if the patient has biliary tract symptoms or significant abdominal pain ( Figure 1 ),10

Why do diabetics have bowel problems?

Diabetic Enteropathy – Enteropathy means disease of the intestine. You’re more likely to have it if you have gastroparesis. If you’ve had diabetes for a long time, you might also have problems with your small intestine, colon, or rectum. Diabetes-related damage to nerves in the intestines causes the food you eat to slow down or stop as your body processes it.

  1. That leads to constipation, and creates a breeding ground for unhealthy bacteria.
  2. As a result, you might have diarrhea (or a combination or constipation/diarrhea, which is the most common symptom of enteropathy).
  3. Stool might leak from your rectum, and you may find it hard to control bowel movements,

The problem may get worse after you eat. Your doctor will probably want to rule out other possible causes of your problem, like diet, medications, or diseases such as a thyroid disorder, If you have diabetic enteropathy, your doctor will try to find ways to help keep your blood sugar stable and control your symptoms.

What organ does diabetes affect the most?

Overview – Type 2 diabetes is an impairment in the way the body regulates and uses sugar (glucose) as a fuel. This long-term (chronic) condition results in too much sugar circulating in the bloodstream. Eventually, high blood sugar levels can lead to disorders of the circulatory, nervous and immune systems.

In type 2 diabetes, there are primarily two interrelated problems at work. Your pancreas does not produce enough insulin — a hormone that regulates the movement of sugar into your cells — and cells respond poorly to insulin and take in less sugar. Type 2 diabetes used to be known as adult-onset diabetes, but both type 1 and type 2 diabetes can begin during childhood and adulthood.

Type 2 is more common in older adults, but the increase in the number of children with obesity has led to more cases of type 2 diabetes in younger people. There’s no cure for type 2 diabetes, but losing weight, eating well and exercising can help you manage the disease.

What is diabetic tummy?

What is Diabetic Gastroparesis? Gastroparesis is a chronic condition where the stomach has trouble clearing things out of it because of damage to the stomach muscles. In diabetic gastroparesis, nerve damage caused by high blood sugar can make stomach muscles too slow or not work at all.

Does diabetes make you poop less?

Constipation is a relatively common complaint among people living with diabetes. Diabetes can cause constipation either directly or indirectly. Diabetes can lead to persistently high blood sugar levels, which may cause nerve damage that can result in constipation,

What triggers diabetic gastroparesis?

History and Physical – Nausea is the most common symptom in gastroparesis. Other common symptoms include vomiting, early satiety, postprandial fullness, and bloating. Vomitus often contains undigested chewed food. Both weight loss and weight gain can occur.

Does diabetes occur in the digestive system?

How Diabetic Neuropathy Can Lead to Heartburn and Other Issues – So how might diabetes affect the digestive system? “Advanced diabetes, whether it’s from type 1 or type 2 diabetes, can affect any organ in the body — including those organs in the digestive tract,” says James C.

  • Reynolds, MD, a gastroenterology specialist and clinical medicine professor at the University of Pennsylvania in Philadelphia. Dr.
  • Reynolds notes digestive problems may be caused by the very factors that led to diabetes in the first place, such as obesity, but it’s also possible that digestive problems are the result of diabetes-related complications, such as hyperglycemia, or high blood sugar,

One of the most serious diabetes complications that can result from consistent high blood sugar is diabetic neuropathy, or nerve damage. Neuropathy may lead to weakness, pain, and numbness, affecting feeling in your feet, legs, and hands, but the condition can also affect digestive functions like swallowing and constipation, Reynolds explains.

Does blood sugar affect bowel movements?

– The connection between diabetes and diarrhea isn’t clear. Research suggests the following factors may play a role:

Celiac disease and microscopic colitis: People with diabetes appear to have a higher risk of these conditions. The only symptom may be diarrhea. Sugar-free sweeteners and other ingredients: Consuming these products may increase the risk of diarrhea. Sorbitol, mannitol, and xylitol, for example, can have a laxative effect. Neuropathy: High blood sugar levels can lead to nerve damage. If this affects the nerves of the small intestine, it can lead to diarrhea, especially at night. Neuropathy can also affect anorectal function, making fecal incontinence more likely. Pancreatic function: Diabetes affects how the pancreas works. This can lead to gastrointestinal disturbances. People with diabetes are two to four times more likely to experience pancreatitis, for instance, than those without diabetes. Diarrhea is a symptom of pancreatitis. Diabetic enteropathy: This is a condition that affects the large intestine. It can cause diarrhea, constipation, and fecal incontinence. It’s more likely to occur in people with diabetes than those without. Diabetes medication: Metformin, statins, and other drugs you might be taking for diabetes and related conditions can affect how your intestines work. Research suggests 15% to 24% of people who take metformin may have diarrhea. Bacterial overgrowth: This happens when certain types of bacteria become too plentiful in the gut. It can occur with diabetic enteropathy.

People with diabetes can also have the same causes of diarrhea as people without diabetes, such as :

allergies and food intolerances, such as to dairy and fructoselong-term use of antibiotics, which can affect the makeup of the gut microbiotamedications, such as antacids containing magnesium and some cancer therapies

How long does it take for diabetes to cause organ damage?

Kidney damage may begin 10 to 15 years after diabetes starts. As damage gets worse, the kidneys become worse at cleansing the blood. If the damage gets bad enough, the kidneys can stop working. Kidney damage can’t be reversed.

How do I know if my diabetes is getting worse?

Final Words – These are some signs that your type 2 diabetes is getting worse. Other signs like a tingling sensation, numbness in your hand or feet, high blood pressure, increase in appetite, fatigue, blurred vision, trouble seeing at night, and more shouldn’t be overlooked.

Just as you would visit a clinic for allergy testing charlotte when you notice any symptoms, you should do the same if any of the mentioned signs show up.

How do you get rid of diabetic gut?

Eggs Make for a Filling and Healthy Breakfast That Fights Belly Fat – “A diet with adequate protein is beneficial for reducing belly fat,” says Norwood. “Studies have shown that people who eat more protein have less belly fat.” Protein is an important nutrient for satiety, and a January 2012 study in Nutrition & Metabolism shows that eating high-quality protein, like the type found in eggs, is linked with lower belly fat.

  1. Eating enough protein while following a lower-carbohydrate diet can be an effective way to feel full, control blood sugar, improve insulin sensitivity, and ultimately, reduce or prevent belly fat,” Norwood says.
  2. RELATED: Are Eggs Safe for People With Diabetes to Eat? But don’t eat just protein: Meals should contain a combination of protein, fat, and high-fiber carbohydrates, says Zanini, who suggests an example meal of two scrambled eggs with sautéed asparagus and mushrooms paired with ¼ avocado, sliced, and 1 cup berries,

Also important to note is that, while beneficial, eating too much protein can contribute to weight gain and affect glucose control, according to a review published in November 2014 in Nutrition & Metabolism, Therefore, be sure to consult your registered dietitian or certified diabetes educator to figure out how much protein to factor into your overall daily calorie count.

Does diabetes cause small intestine bacterial overgrowth?

Introduction – Small intestinal bacterial overgrowth (SIBO) is a condition that is defined as excessive colonization of Gram-negative aerobic and anaerobic bacteria in the proximal small bowel. A jejunal aspiration culture is considered to be the gold standard diagnostic test for SIBO.

  • However, the H 2 /CH 4 breath test is more readily available, safe, inexpensive, and noninvasive compared with the jejunal aspiration culture for the diagnosis of SIBO.
  • Therefore, the H 2 /CH 4 breath test is currently used in clinical practice.
  • SIBO and intestinal microbiota have been associated with various diseases, such as Crohn’s disease, irritable bowel syndrome, 1, 2 functional gastrointestinal disorders, 3 deep venous thrombosis, 4 nonalcoholic fatty liver disease, 5 – 7 and diabetes.8, 9 Type 2 diabetes (T2DM) is a metabolic disease that is characterized by decreased insulin secretion and variable degrees of peripheral insulin resistance, which leads to hyperglycemia.

Recently, many studies focused on a new mechanism where SIBO is involved in the development of T2DM. Most studies suggest that diabetic patients have a higher incidence of SIBO, especially in patients with T2DM combined with diabetic peripheral neuropathy.9, 10 SIBO has been associated with an increased risk of diabetic complications and T2DM severity.

Gastrointestinal complications are common in longstanding T2DM patients.11, 12 Marked hyperglycemia decreases the motility index and propagation of duodenal and jejunal waves and slows small-intestinal transit.13 – 15 Previous studies established that gastrointestinal symptoms in SIBO-positive patients with chronic abdominal pain or diarrhea and weak blood glycemic control in T2DM patients may be improved after treatment of SIBO.16, 17 Multiple mechanisms, including glucotoxicity, lipotoxicity, oxidative stress, endoplasmic reticulum stress, and amyloid deposits in the islets, 18 – 20 are involved in the impaired insulin function in T2DM, which are strongly associated with glycemic control and the severity of T2DM.

There is a lack of studies that have evaluated the association between beta-cell function of T2DM and SIBO. We hypothesized that SIBO is associated with insulin secretion. Therefore, the aim of the study was to evaluate whether beta-cell function was associated with SIBO.

Can diabetes cause gut inflammation?

People with Type 1 diabetes exhibit inflammation in the digestive tract and gut bacteria­—a pattern that differs from individuals who do not have diabetes or those who have celiac disease, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism,

Type 1 diabetes occurs when the body produces little to no insulin. The hormone plays a crucial role in carrying blood sugar to the body’s cells. Type 1 diabetes tends to begin affecting people at a young age. It typically develops when the body’s own immune system attacks the pancreas and prevents the gland from producing insulin.

As a result, Type 1 diabetes is an autoimmune condition. Among every 1,000 American adults, between one and five people have Type 1 diabetes, according to the Society’s Endocrine Facts and Figures report, “Our findings indicate the individuals with Type 1 diabetes have an inflammatory signature and microbiome that differ from what we see in people who do not have diabetes or even in those with other autoimmune conditions such as celiac disease,” said the study’s senior author, Lorenzo Piemonti, MD, of the Diabetes Research Institute at San Raffaele Hospital in Milan, Italy.

“Some researchers have theorized that the gut may contribute to the development of Type 1 diabetes, so it is important to understand how the disease affects the digestive system and microbiome.” The study examined the microbiome of 54 individuals who underwent endoscopies and biopsies of the first part of the small intestine, known as the duodenum, at San Raffaele Hospital between 2009 and 2015.

The individuals were either undergoing a diagnostic procedure to diagnose a gastrointestinal disorder or volunteered to participate in the study. This approach allowed researchers to directly assess the gastrointestinal tract and bacteria, unlike studies that rely on stool samples for analysis.

  1. The analysis of tissues sampled from the endoscopy produced high-resolution snapshots of the innermost layer of the gastrointestinal tract.
  2. Individuals with Type 1 diabetes showed significantly more signs of inflammation of the gut’s mucous membrane linked to 10 specific genes than the participants who had celiac disease and control healthy subjects.

Participants with Type 1 diabetes also displayed a distinct combination of gut bacteria that was different from the other two groups. “We don’t know if Type 1 diabetes’ signature effect on the gut is caused by or the result of the body’s own attacks on the pancreas,” Piemonti said.

“By exploring this, we may be able to find new ways to treat the disease by targeting the unique gastrointestinal characteristics of individuals with Type 1 diabetes.” The study, ” Duodenal Mucosa of Patients with Type 1 Diabetes Shows Distinctive Inflammatory Profile and Microbiota,” will be published online at, ahead of print.
