EFFECTS Peristalsis
Reflexive relaxation
Sphincter tone
Vascular flow
Intestinal segmentation
![Page 10: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/10.jpg)
MOST COMMON PROBLEMS Constipation
Diarrhea
Abdominal pain
Nausea
Vomiting
![Page 11: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/11.jpg)
ESOPHAGUS• Abnormal Motility (50-75%)
• Reduced number, amplitude & velocity of peristalsis
• Increased spontaneous, spastic and repetitive contractions
• Appearance of multipeaked contractions
•Impaired(prolonged) esophageal transit- scintigraphy
• Reduced lower esophageal sphincter pressure
![Page 12: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/12.jpg)
Hyperglycemia impairs neutrophil function and opsonization.
Odynophagia ® Nystatin 1lakh U-3-5times/dy, Clotrimazole
10mg(troche) 5 times/dy or 500mg VT HS. Fluconazole- 200mg loading + 100mg/dy x
21dys
![Page 13: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/13.jpg)
STOMACH
Type 1: Gastritis/Gastric Atrophy (5% to 10%).
Parietal cell antibodies (15% to 25%).
Pernicious Anemia (2.6% to 4%).
Reduced acid hence decreased ulcer incidence.
Increased risk of ulcer bleeding- microcirculatory changes that impair mucosal integrity.

GASTROPARESIS DIABETICORUM
Seen in upto 60% Insidious nature, Rarely acute- similar to vagotomy Nausea, vomiting, pain, bloating, early satiety, flatulence, anorexia and postprandial regurgitation- 20% Changes in drug absorption Food retention- increase of bacteria toxins & fermentation products- hypermotility and diarrhoeaExamination - succussion splash
![Page 16: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/16.jpg)
● Scintigraphy- Solid and liquid emptying assessed.Gastroparesis->60% @ 2hrs & >10% @
4hrs.
● Saline loading- 800-1000ml.
● EGG- Increased frequency of antral dysrhythmias. Phase 3 MMC are absent →bezoars.

● Abnormal Gastroduodenal pressure gradient
Fundal relaxation
Pylorospasm

TREATMENTGlycemic control- Depo-insulin to prevent hypoglycaemic episodes
DIET MODIFICATION:
Smaller/liquid meals, low-fat, low-fiber diet
Jejunal tube feeding/ TPN
MEDICATIONS-
Prokinetics: Metoclopramide10to20mg, Erythromycin 125mgBD or TDS or IV200mg over5to10minutesTDS, Domperidone 10 to 30 mg.
Antiemetics- (promethazine or prochlorperazine), scopolamine patch.
Low-dose TCA
5-HT3 receptor antagonists- odansetron, dronabinol
Ghrelin- improves gastric emptying
![Page 19: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/19.jpg)
GES
A) Gastric pacing - improves gastric emptying
B) Neurostimulation - controls nausea/vomiting
Endoscopic therapy with injection of botulinum toxin into the pyloric sphincter
Gastric resection (Partial or complete) in medically refractory cases
![Page 20: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/20.jpg)
GASTRIC ELECTRICAL STIMULATION-10 YEAR DATA
- Greater Symptom Reduction- Improved Gastric Emptying normalized in 23%- Decreased Hb A1C levels translates to fewer complications- Significant Weight Gain- Reduction in Hospitalization Days- Reduced Medication Usage (for gastroparesis)
McCallum, et al, Clin. Gastro & Hep. 9(4):314-319
![Page 21: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/21.jpg)
TABETIC PAIN sharp, sudden pain
With nausea, vomiting, anorexia and weight loss-mimics intra-abdominal malignancy
Diabetic radiculopathy of thoracic nerve roots
The diagnosis- abnormal EMG of the anterior abdominal wall muscles
![Page 22: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/22.jpg)
DIABETIC ACIDOSIS
Anorexia, nausea and vomiting- 75%
Gastric dilatation- reduced gastric motility→vomiting-(ketones and systemic acidosis)
Abdominal pain-Acute apendicitis, Acute pancreatitis-should be excluded
![Page 23: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/23.jpg)
DIARRHEA Drugs- Metformin, ά-Glucosidase
inhibitors ,sugarfree sweeteners. SIBO Pancreatic insufficiency Fast transit (and hyperthyroidism) Celiac disease(4%) Hormones- glucagon or somatostatin Autonomic neuropathy
![Page 24: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/24.jpg)
CHRONIC DIARRHEA WITHOUT STEATORRHEA
Occur 5-10 years later, men > women: 22%
Exact pathogenesis- still undetermined
In young-long standing and uncontrolled diabetes.
Diabetic night diarrhoea
Hyperglycaemia, hypoglycemia and ketoacidosis.
Barium transit- segmentation with mucous villous atrophy, irregularity.
![Page 25: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/25.jpg)
DIABETIC DIARRHEA WITH STEATORRHEA
Steatorrhea occurs when diarrhoea worsens: 75%
Shows intermittent flow.
More frequently, postpardial and they appear at night
Rarely fatty, watery and abundant
![Page 26: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/26.jpg)
TREATMENT Strict control of blood glucose Broad spectrum antibiotics Vitamins, folic acid, liver extracts, bismuth, opiates, atropine Corticosteroids Clonidine (0.1 to 0.6 mg twice daily) stimulate intestinal
absorption Octreotide (50 to 100 subcutaneously, BD) in refractory
diabetic diarrhea Codeine sulfate (30 mg every six to eight hours), Diphenoxylate with atropine (Lomotil), Loperamide Psyllium hydrophilic mucilloid
![Page 27: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/27.jpg)
DIABETES AND CELIAC DISEASE Coexist (4%)-shared HLA class II genes and non-HLA
loci Found within 4 years of DM. Short stature, pubertal delay, - signs of vitamin deficit,
anemia, losing weight and pigmentation,osteoporosis, and/or reproductive disorders
Have poor glycemic control- hypoglycemic episodes, and microvascular complications.
Small intestine which shows villous atrophy and abnormal superficial epithelium
Malabsorbtion in diabetes-limited only to fats Respond to gluten free diet
![Page 28: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/28.jpg)
LARGE INTESTINE Constipation Impaired gastrocolic reflex and delayed colonic
transit Ischemic colitis - luminal narrowing of
submucosal arterioles. Neuropathy damages the motility. Equally frequent and severe without
neuropathy Obstipation- nausea, vomiting, belching and
bloating.
![Page 29: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/29.jpg)
MEGASIGMOID SYNDROME
Colon dilatation- neuropathy and the paralysis of ganglia.
Imitates acute intestinal pseudo-obstruction.
Obstipation- long standing and refractory. X-ray- dilatation of sigmoid colon. Mucosa of the large intestine- Normal. Bad prognosis. Treatment- Laxative (abuse).
![Page 30: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/30.jpg)
FECAL INCONTINENCE The total stool volume is normal. Steatorrhea in 30%. Impaired internal anal sphincter resting tone and
reflexive internal sphincter relaxation. Reduced sensitivity of the rectum to distension. Management:
Antidiarrheal therapyBiofeedback trainingSacral nerve stimulationSurgeryIn some patients incontinence remits spontaneously.
![Page 31: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/31.jpg)
DIABETES – LIVER/BILIARYHIGHER INCIDENCE OF ACUTE HEPATITIS B-1.4 vs 0.7 per 100,000 patients
HCV- patients have an increased risk of type 2 DM.GALL BLADDER: acute cholecystitis postoperative complications are higher
GALLSTONES MORE FREQUENT (2X)
lithogenic bile
hypomotility
prophylactic cholecystectomy.- not recommended
SOMATOSTATINOMA Triad- Gallstones, Diabetes, Diarrhea/Steatorrhea
STEATOSIS in upto 80%
DM is a risk factor for HCC.
![Page 32: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/32.jpg)
DIABETES -NAFLDSpectrum of disease:
Simple steatosissteatohepatitis(NASH) cirrhosis(20%).
Increase the risk of acute hepatic failureRisk Factors: female, diabetes, obesity, hyperlipidemia
Fatty deposition, nuclear vacuolisation, cellular infiltration and fibriosis
Cryptogenic cirrhosis 70% obese/50% diabetic!!
Cirrhosis of the liver may precede or cause diabetes→ glucose intolerant & 30%-60% develop DM
![Page 33: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/33.jpg)
TREATMENT- Slow/gradual weight loss
- Control diabetes/hyperlipidemia
- Pharmacologic treatment: TZD’s, others
- Surgery:
Bariatric - improvement in 90%
Liver transplant(Cirrhotics)
![Page 34: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/34.jpg)
PANCREAS DM for more than 5 years Pancreatitis can produce diabetes Exocrine pancreas secretion- Deteriorates
Diabetes and pancreatitis:Causes hyperglycemiaMay persist for several monthsPancreatic calcificationsDegenerative complications-less frequent
Exocrine secretion-reduced volume & enzymes
![Page 35: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/35.jpg)
GALL BLADDER Higher incidence- unexplained
Defect in the cholinergic pathway
Reduced α-adrenergic tone
Deficiency of cholecystokinin receptors
Arteriolar disease impairing muscle contraction
Hyperglycemia
Hyperinsulinemia
![Page 36: DIABETES AND GASTROINTESTINAL TRACT](https://reader036.fdocuments.net/reader036/viewer/2022062522/58d088f91a28ab012d8b600b/html5/thumbnails/36.jpg)
CARCINOMAS Insulin resistance→secondary hyperinsulinemia →
↓IGF-binding proteins → ↑IGF-1 & Growth hormone → cancer growth(Pancreas, liver & colon).
Loss of weight and deteriorated glycoregulation.
New onset diabetes >50 yrs.
HbA1c > 7.5% → young age, more advanced tumor and poorer survival.
Slow bowel transit time increase carcinogen exposure
