Crohn's disease fasting diet
Patients with Crohn's disease have inflammatory lesions in their intestines, which decreases their digestive and absorptive functions. Special attention should be paid to their diet. Consuming cold, spicy, and irritating foods, such as peppers, mustard, alcohol, strong tea, and coffee, should be reduced. Foods that cause gas, like leeks and bean products, should also be minimized, as well as carbonated drinks like cola or coffee. It is advisable to eat more vegetables, such as carrots and yams. Nutritional intake should focus on high-nutrient, low-fat foods like lean meats, eggs, and fish. During the treatment period, ample rest is essential.
Does colitis cause a fever?
Colitis is caused by bacterial or viral infections in the colon, and infections are the most common cause of fever; therefore, patients with colitis often experience fever. Some pathogens invade the human body and act on the temperature regulation center, raising the set point, which results in fever. If the body temperature does not exceed 38.5°C, physical methods can be used to reduce the fever, such as wiping the palms, soles, forehead, and armpits with a warm towel, while actively using medication to treat colitis. If the body temperature is higher, some antipyretic drugs can be used along with the treatment for colitis.
Appendicitis how many days to be discharged
The length of hospital stay after appendicitis treatment varies greatly depending on the individual's constitution, the severity of the appendicitis, and the method of treatment used. If the symptoms are mild and only conservative medication treatment is chosen, then you can be discharged after the symptoms disappear. If surgical treatment is chosen, then it's typical to observe for three to five days post-surgery; if there are no significant signs of infection or pus formation, then discharge can be considered, followed by observational treatment. If there is significant pus formation, or cases of gangrene or perforation that lead to severe peritonitis, routine anti-infection treatment should be administered post-surgery. Therefore, the treatment period may be longer, requiring a waiting period until the inflammation is completely resolved before discharge.
Does acute gastroenteritis cause constipation?
Acute gastroenteritis refers to acute inflammation of the gastrointestinal tract, characterized by abdominal pain, nausea, and vomiting. This condition does not involve constipation. In cases of mild diarrhea caused by acute gastroenteritis, the general condition is good, with fewer than ten bowel movements, and the stool sometimes appears like egg drop soup. For more severe diarrhea, there might be more than ten bowel movements per day, and treatment should primarily focus on antidiarrheal, pain relief, and antiemetic medications. It is also important to rest adequately, hydrate promptly, and follow a diet of eating small, frequent meals. If the condition is severe, treatment might involve gastrointestinal decompression and parenteral nutrition.
Is appendicitis contagious?
Appendicitis is an inflammation that occurs in the lumen of the appendix, including acute appendicitis and chronic appendicitis. Appendicitis is not contagious, as it is not an infectious disease, but rather a purulent inflammation. Therefore, there is no need to isolate patients with appendicitis. Appendicitis usually requires surgical removal, but it is important to note that surgery should not be performed if acute appendicitis has been present for more than 72 hours, or if an abscess has formed. The majority of surgeries are performed using laparoscopic appendectomy, a method which allows for a faster recovery post-operation.
Crohn's disease is what kind of disease?
Crohn's disease is an inflammatory bowel disease primarily affecting the terminal ileum and the right half of the colon. Typical symptoms include abdominal pain, diarrhea, intestinal obstruction, and it may also lead to complications such as intestinal perforation or rectal bleeding. Additionally, it can affect joints, skin, liver, and other organs. The course of the disease is often recurrent and difficult to cure completely. Currently, there are no specifically effective drugs. Severe complications may require surgical treatment. Mild symptoms can be controlled with medication. Dietary guidelines suggest eating small, frequent meals that are high in nutrition and low in fat, and it is important to consume more vegetables and supplement with vitamin C.
How is appendicitis surgery done?
Appendicitis currently primarily involves two surgical methods. One is appendectomy via laparoscopy, and the other is the traditional method involving an incision at McBurney's point to remove the appendix. While the surgical methods differ, the principle behind the surgery is the same: in the abdominal cavity, the appendix is separated from the mesentery, then the appendiceal artery is ligated and the appendix is removed from the base. The stump is disinfected with iodine, and purse-string sutures are used to wrap the stump. If there is an appendiceal perforation causing diffuse peritonitis, it is necessary to thoroughly clean the pus from the abdominal cavity, then check that no surgical instruments are left inside before closing the abdomen. Postoperatively, the use of antibiotic medication depends on the patient's condition, and a minimum rest period of two weeks is required. (The use of medications should be under the guidance of a doctor.)
How to diagnose appendicitis
Appendicitis is primarily diagnosed clinically through a physical examination. The patient is asked to lie flat, exposing the abdomen, with legs bent. The doctor stands on the patient’s right side and uses the right hand with fingers together to gently rub the abdomen, pressing on the McBurney's point. If there is significant pain, this is considered positive tenderness. Then, the doctor quickly lifts the fingers; if there is significant rebound pain, it is generally confirmed as acute appendicitis. During acute appendicitis, as the appendix lumen expands and the appendix becomes congested and edematous, ultrasound imaging can also show corresponding signs that serve as an auxiliary diagnosis. Once acute appendicitis is confirmed, it is mostly treated surgically.
How to care for gastric ulcer bleeding
Gastric ulcer bleeding is a relatively common complication. First, it is important to soothe the patient's emotions, encourage rest, reduce mental stress, and pay attention to significant bleeding, which can cause vomiting of blood. It is necessary to promptly clean the blood stains in the mouth to prevent aspiration, provide timely symptomatic treatment, and choose to use proton pump inhibitors combined with endoscopic hemostasis. Vascular intervention or surgery may be required when necessary. Dietary management should be strengthened, with regular meals, consumption of soft, easily digestible food, and avoidance of hard, cold foods. It is crucial to strictly abstain from smoking and alcohol, and to consume less strong tea, coffee, etc., while actively treating any complications. (Please use medications under the guidance of a doctor.)
How to relieve pain from acute appendicitis
For rapid pain relief in acute appendicitis, one can choose antispasmodic or sedative medications. However, it is important to note that acute appendicitis often requires surgical treatment clinically. If the pain is not particularly severe, conservative medication treatment can also be chosen, using sensitive antibiotics for anti-inflammatory pain relief. If surgery involves appendectomy, laparoscopic appendectomy is generally chosen, which has less intraoperative bleeding and quicker postoperative recovery. Only after the appendix is removed can the onset of acute appendicitis be effectively controlled or the transition from acute to chronic appendicitis prevented. (Specific medications should be used under the guidance of a physician.)
