Is upper gastrointestinal bleeding colon cancer?
Upper gastrointestinal bleeding cannot be caused by colon cancer, as the colon is part of the lower gastrointestinal tract. Therefore, upper gastrointestinal bleeding cannot result from colon cancer. There are several diseases that can cause upper gastrointestinal bleeding: The first common cause is peptic ulcer, including both gastric ulcers and duodenal ulcers, which can lead to bleeding in the upper gastrointestinal tract. The second cause is bleeding due to esophageal or gastric varices rupture associated with liver cirrhosis. This type of bleeding can be substantial and sometimes life-threatening. The third cause is acute gastric mucosal injury, such as that caused by heavy alcohol consumption or the use of nonsteroidal anti-inflammatory drugs (NSAIDs). The fourth cause is gastric cancer, which can lead to upper gastrointestinal tract bleeding. While colon cancer can cause rectal bleeding, it is not a cause of upper gastrointestinal tract bleeding.
What should I do about moderate fatty liver?
In cases of moderate fatty liver, it is essential to be very cautious about diet, strictly abstaining from smoking and drinking, and avoiding greasy foods. Additionally, engaging in appropriate physical exercise is advisable, ideally maintaining over half an hour of activity daily, which can boost immunity and prevent weight gain, potentially exacerbating the condition otherwise. Fatty liver is a reversible disease, but if not promptly addressed, it can progress to cirrhosis. Therefore, a light diet should be the primary focus, avoiding fried foods and high-fat foods, including animal organs. Regular follow-up visits to the hospital are also necessary.
Does the breath test for Helicobacter pylori require fasting?
Currently, the detection of Helicobacter pylori is highly accurate and specific, and a rapid, simple, and effective method is the Carbon-14 breath test. The Carbon-14 breath test requires no eating within six hours, so it is best to take it on an empty stomach. Therefore, it is preferable to test for Helicobacter pylori on an empty stomach. Currently, the infection rate of Helicobacter pylori in our country has exceeded 50%. Helicobacter pylori is the principal cause of chronic gastritis, peptic ulcers, or gastric cancer. Therefore, if symptoms of the digestive system occur, such as belching, acid reflux, upper abdominal pain, nausea, and poor appetite, it is advisable to conduct a test for Helicobacter pylori, specifically the Carbon-14 breath test, to confirm the infection of Helicobacter pylori.
Symptoms of mild colitis
Chronic colitis is characterized by symptoms such as abdominal pain, diarrhea, and sometimes mucus in the stool resembling nasal discharge. These symptoms do not vary between mild or moderate to severe cases, as both mild and severe chronic colitis exhibit similar symptoms, making it impossible to distinguish between the severity from the symptoms alone. It is only possible to determine whether chronic colitis is mild or severe during a colonoscopy by observing the degree of mucosal hyperemia, edema, and erosion. Therefore, to differentiate whether chronic colitis is mild or severe, a definitive diagnosis must be made through a colonoscopy examination.
How to treat duodenal ulcer with Helicobacter pylori infection?
The treatment of duodenal ulcer accompanied by Helicobacter pylori infection begins primarily with anti-Helicobacter pylori therapy. The regimen includes a proton pump inhibitor, two types of antibiotics, and a bismuth agent, lasting a total of 14 days. In addition, for duodenal ulcers, it is necessary to use acid-suppressing and stomach-protecting medications to promote gastric mobility and protect the gastric mucosa, with the treatment course lasting six weeks. At the same time, it is important to focus on a light and easily digestible diet, avoiding smoking and drinking alcohol, as well as avoiding strong tea, coffee, spicy, irritating, fried, grilled, raw, cold, and sweet foods. It is also crucial to avoid adverse emotional effects such as anxiety, depression, and stress, prevent excessive fatigue or staying up late, and it is advised to moderately increase physical activity.
Can a CT scan check for Irritable Bowel Syndrome?
Irritable Bowel Syndrome (IBS) is the most common type of functional gastrointestinal disorder, characterized primarily by abdominal pain accompanied by changes in habitual bowel patterns. The abdominal pain is related to defecation, often improving after bowel movements, and the symptoms frequently recur or are chronically persistent. Thus, IBS is a functional disease, meaning it does not involve organic changes. In other words, medical examinations do not reveal problems in any specific part of the body. Therefore, IBS cannot be detected with a CT scan, and CT also cannot visualize the intestinal mucosa. Even diseases like chronic colitis cannot be detected with a CT scan. Any diseases involving the gastrointestinal mucosa cannot be uncovered by CT, hence diagnosis requires the use of gastroscopy or colonoscopy.
Is moderate fatty liver serious?
Moderate fatty liver is considered a relatively severe condition, mainly caused by the excessive accumulation of fat tissue in the liver. Generally, moderate fatty liver can cause varying degrees of inflammatory changes in liver cells. It can be roughly divided into three stages: the first stage is simple fatty liver, the second stage is steatohepatitis, and the third stage is fatty liver fibrosis, also known as steatotic liver cirrhosis. Many factors can cause fatty liver, such as obesity, alcohol consumption, and drug toxicity. If a patient experiences indigestion, diarrhea, or loss of appetite, the possibility of fatty liver should be considered. It is advisable to visit a hospital for an upper abdominal CT scan or an abdominal ultrasound to confirm the diagnosis. The treatment mainly involves three aspects: removing the cause, dietary adjustment, and medication.
How to treat Helicobacter pylori positive?
The infection rate of Helicobacter pylori in our country has already exceeded 50%, and Helicobacter pylori has been confirmed as the main cause of chronic gastritis, peptic ulcers, and even gastric cancer. If Helicobacter pylori tests positive and is accompanied by symptoms or diseases of the digestive system, eradication treatment for Helicobacter pylori is necessary. The medication involves a proton pump inhibitor, two types of antibiotics, and a bismuth agent, with a treatment period of 14 days. After the 14-day treatment, the medication should be discontinued for a month before rechecking with a carbon-14 breath test to confirm whether Helicobacter pylori has turned negative. If it has turned negative, it indicates that the eradication treatment of Helicobacter pylori is successful. After infection with Helicobacter pylori, a diet easy to digest is recommended.
What are the complications of late-stage liver cirrhosis?
Late-stage cirrhosis can lead to many complications, such as bleeding from esophageal and gastric varices, which is one of the more common and severe complications of cirrhosis. Other complications include spontaneous peritonitis, liver cancer, hepatorenal syndrome, hepatic encephalopathy, portal vein thrombosis, and symptoms like ascites, palmar erythema, and spider angiomas. Additionally, there may be symptoms such as dark skin or hyperpigmentation and jaundice. Once cirrhosis is diagnosed, timely intervention and treatment are necessary to delay the progression of the disease.
Symptoms of gastritis
Gastritis is divided into two types: acute gastritis and chronic gastritis. The main cause of acute gastritis is bacterial or viral infection, with primary symptoms including abdominal pain, nausea, vomiting, and fever. Chronic gastritis is mainly caused by the digestion of the stomach itself due to stomach acid and pepsin. Its main cause is closely related to infection by Helicobacter pylori, with primary symptoms being upper abdominal distension, belching, acid reflux, nausea, vomiting, heartburn, poor appetite, and indigestion. For acute gastritis, a routine blood test is necessary to confirm the diagnosis. For chronic gastritis, a gastroscopy and a carbon-14 breath test are required to determine if there is an infection with Helicobacter pylori, which are the main examinations.
