Eva W Constipation has many causes. Common causes include slow movement of stool within the colon, irritable bowel syndrome, and pelvic disorders. Underlying associated diseases include hypothyroidism, diabetes, Parkinson's disease, colon cancer, diverticulitis, and inflammatory bowel disease.[3][4] Medications associated with constipation include opioids, certain antacids, calcium channel blockers, and anticholinergics.[3] Of those taking opioids about 90% develop constipation.[5] Constipation is more concerning when there is weight loss or anemia, blood is present in the stool, there is a history of inflammatory bowel disease or colon cancer in a person's family, or it is of new onset in someone who is older.[6]
Krystal H 便秘通常有許多成因,常見原因包含內有糞便的結腸運動得很慢、患有腸躁症或骨腔疾病等,相關的潛在性疾病包含甲狀腺功能減退症、腹瀉、帕金森氏症、結腸癌、憩室炎、炎症性腸病[3][4] 等,導致便秘的藥物治療包含服用鴉片類藥物、特定抗酸藥、鈣通道阻滯劑以及抗膽鹼劑[3] ,大約90%服用鴉片藥物的患者會發生便秘[5]。當便秘患者發生下述情況時將需要進一步的觀察,如便秘體重減輕、貧血、糞便帶血,家族病史中有人擁有炎症性腸病或結腸癌者,或初發時患者年事已高等。[6]
Eva W Treatment of constipation depends on the underlying cause and the duration that it has been present. Measures that may help include drinking enough fluids, eating more fiber, and exercise. If this is not effective laxatives of the bulk forming agent, osmotic agent, stool softener, or lubricant type may be recommended. Stimulant laxatives are generally reserved for when other types are not effective. Other treatments may include biofeedback or surgery.[3]

Eva W Typhus, also known as typhus fever is a group of infectious diseases that include epidemic typhus, scrub typhus, and murine typhus. Common symptoms include fever, headache, and a rash.[1] Typically these begin one to two weeks after exposure.[2]
They are caused by a bacterial infection. Epidemic typhus is due to Rickettsia prowazekii spread by body lice, scrub typhus is due to Orientia tsutsugamushi spread by chiggers, and murine typhus is due to Rickettsia typhi spread by fleas.[1]
There is no vaccine. Prevention is by reducing exposure to the organisms that spreads the disease.[3][4][5] Treatment is with the antibiotic doxycycline.[2] Epidemic typhus generally occurs in outbreaks when poor sanitary and crowding are present.[6]Well once common, it is now rare.[3] Scrub typhus occurs in Southeast Asia, Japan, and northern Australia.[5] Murine typhus occurs in tropical and subtropical areas of the world.[4]
Typhus has been described since at least 1528. The name comes from the Greek typhus (τύφος) meaning hazy, describing the state of mind of those infected.[7] While "typhoid" means "typhus-like", typhus and typhoid fever are distinct diseases caused by different types of bacteria.[8]
