FLATULENCE:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
If the gas is eructated, stools for occult blood and an upper GI series and esophagogram should be ordered. These may disclose a hiatal hernia and esophagitis, a gastric or duodenal ulcer, and other upper intestinal disorders. A gallbladder series may be done if the upper GI series is unremarkable. Gastroscopy and esophagoscopy may be necessary, as well as a gastric analysis.
If the excessive gas is passed rectally, stools for occult blood, stools for ovum and parasite, and stool cultures should be done. A flat plate of the abdomen may disclose evidence of intestinal obstruction. If these are negative, a barium enema may be done and that may be followed with a small bowel series. Colonoscopy may be indicated. Analysis of flatus for volume and composition of intestinal gases may be helpful. A quantitative stool-fat analysis should be done to determine if there is steatorrhea, and if so, the workup would proceed. A lactose tolerance test can be done in cases suspected of lactase deficiency. Hydrogen breath testing is useful in detecting lactase deficiency and other carbohydrate intolerance and bacterial overgrowth. When extensive testing is negative, a psychiatrist may need to be consulted.

Abdominal distention:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If the patient’s abdominal distention isn’t acute, ask about its onset and duration and associated signs. A patient with localized distention may report a sensation of pressure, fullness, or tenderness in the affected area. A patient with generalized distention may report a bloated feeling, a pounding heart, and difficulty breathing deeply or when lying flat. (See Abdominal distention: Common causes and associated findings.)
The patient may also feel unable to bend at his waist. Make sure to ask about abdominal pain, fever, nausea, vomiting, anorexia, altered bowel habits, and weight gain or loss.
Obtain a medical history, noting GI or biliary disorders that may cause peritonitis or ascites, such as cirrhosis, hepatitis, or inflammatory bowel disease. (See Detecting ascites, page 4.) Also, note chronic constipation. Has the patient recently had abdominal surgery, which can lead to abdominal distention? Ask about recent accidents, even minor ones, such as falling off a stepladder.
Perform a complete physical examination. Don’t restrict the examination to the abdomen because you could miss important clues to the cause of abdominal distention. Next, stand at the foot of the bed and observe the recumbent patient for abdominal asymmetry to determine if distention is localized or generalized. Then assess abdominal contour by stooping at his side. Inspect for tense, taut skin and bulging flanks, which may indicate ascites. Observe the umbilicus. An everted umbilicus may indicate ascites or umbilical hernia. An inverted umbilicus may indicate distention from gas; it’s also common in obesity. Inspect the abdomen for signs of inguinal or femoral hernia and for incisions that may point to adhesions. Both may lead to intestinal obstruction. Then auscultate for bowel sounds, abdominal friction rubs (indicating peritoneal inflammation), and bruits (indicating an aneurysm). Listen for succussion splash — a splashing sound normally heard in the stomach when the patient moves or when palpation disturbs the viscera. However, an abnormally loud splash indicates fluid accumulation, suggesting gastric dilation or obstruction.
Next, percuss and palpate the abdomen to determine if distention results from air, fluid, or both. A tympanic note in the left lower quadrant suggests an air-filled descending or sigmoid colon. A tympanic note throughout a generally distended abdomen suggests an air-filled peritoneal cavity. A dull percussion note throughout a generally distended abdomen suggests a fluid-filled peritoneal cavity. Shifting of dullness laterally with the patient in the decubitus position also indicates a fluid-filled abdominal cavity. A pelvic or intra-abdominal mass causes local dullness upon percussion and should be palpable. Obesity causes a large abdomen without shifting dullness, prominent tympany, or palpable bowel or other masses, with generalized rather then localized dullness.
Palpate the abdomen for tenderness, noting whether it’s localized or generalized. Watch for peritoneal signs and symptoms, such as rebound tenderness, guarding, rigidity, McBurney’s point, obturator sign, and psoas sign. Female patients should undergo a pelvic examination; males, a genital examination. All patients who report abdominal pain should undergo a digital rectal examination with fecal occult blood testing. Finally, measure the patient’s abdominal girth for a baseline value. Mark the flanks with a felt-tipped pen as a reference for subsequent measurements.

Dyspepsia:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If the patient complains of dyspepsia, begin by asking him to describe it in detail. How often and when does it occur, specifically in relation to meals? Do drugs or activities relieve or aggravate it? Has he had nausea, vomiting, melena, hematemesis, a cough, or chest pain? Ask if he's taking prescription drugs and if he has recently had surgery. Does he have a history of renal, cardiovascular, or pulmonary disease? Has he noticed a change in the amount or color of his urine?
Ask the patient if he's experiencing an unusual or overwhelming amount of emotional stress. Determine the patient's coping mechanisms and their effectiveness.
Focus the physical examination on the abdomen. Inspect for distention, ascites, scars, obvious hernias, jaundice, uremic frost, and bruising. Then auscultate for bowel sounds and characterize their motility. Palpate and percuss the abdomen, noting tenderness, pain, organ enlargement, or tympany.
Finally, examine other body systems. Ask about behavior changes, and evaluate the patient's level of consciousness. Auscultate for gallops and crackles. Percuss the lungs to detect consolidation. Note peripheral edema and any swelling of the lymph nodes.

Abdominal distention:
History and physical examination
(Professional Guide to Signs & Symptoms (Fifth Edition))
If the patient’s abdominal distention isn’t acute, ask about its onset and duration and associated signs.

Next, stand at the foot of the bed and observe the recumbent patient for abdominal asymmetry to determine if distention is localized or generalized. Then assess abdominal contour by stooping at his side. Inspect for tense, glistening skin and bulging flanks, which may indicate ascites. Observe the umbilicus. An everted umbilicus may indicate ascites or an umbilical hernia. An inverted umbilicus may indicate distention from gas; it’s also common in obese individuals. Inspect the abdomen for signs of an inguinal or femoral hernia and for incisions that may point to adhesions; both may lead to intestinal obstruction. Then auscultate for bowel sounds, abdominal friction rubs (indicating peritoneal inflammation), and bruits (indicating an aneurysm).

Flatulence:
History and physical examination
(Professional Guide to Signs & Symptoms (Fifth Edition))
Determine how long the patient has noticed the flatulence. Find out if he passes an excessive amount of flatus. Also, ask about frequent belching or snoring, and observe for overly rapid speech. These signs are all possible clues to aerophagia.
In addition, be sure to ask the patient if he’s undergoing unusual emotional stress because this can cause aerophagia or irritable bowel syndrome. Obtain a medical history, focusing on GI disorders and systemic illnesses such as scleroderma, which can cause malabsorption syndrome. Then inspect the patient’s abdomen for distention, and auscultate for abnormal bowel sounds. Percuss for increased tympany due to gas accumulation, and palpate for tenderness and masses.

Abdominal distention:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
If the patient's abdominal distention isn't acute, ask about its onset and duration and associated signs. A patient with localized distention may report a sensation of pressure, fullness, or tenderness in the affected area. A patient with generalized distention may report a bloated feeling, a pounding heart, and difficulty breathing deeply or when lying flat.

Obtain a medical history, noting GI or biliary disorders that may cause peritonitis or ascites, such as cirrhosis, hepatitis, or inflammatory bowel disease. (See Detecting ascites.) When did the patient last have a bowel movement? Note chronic constipation. Has the patient recently had abdominal surgery, which can lead to abdominal distention? Ask about recent accidents, even minor ones such as falling off a stepladder.
Perform a complete physical examination. Don't restrict the examination to the abdomen because you could miss important clues to the cause of abdominal distention. Next, stand at the foot of the bed and observe the recumbent patient for abdominal asymmetry to determine if distention is localized or generalized.
