Gallbladder Cancer

#gallbladder cancer, #bile duct cancer, #gallbladder, #gallstones, #cholecystitis, #abdominal ultrasound, #jaundice, #laparoscopy, #stomachache, #tummy ache, #bellyache, #pain inside the abdomen, #feeling of indigestion (food stuck), #bloated feeling in the stomach, #poor digestion

The gallbladder is a small pouch that temporarily stores the digestive fluid (bile) made in the liver. Gallbladder cancer, a malignant tumor that develops there, causes no obvious symptoms until the disease is quite advanced, which makes early detection very difficult. If you have persistent indigestion or abdominal pain, please do not dismiss it on your own; be sure to consult a medical specialist for an examination and detailed tests.

Hearing Loss

#hearing loss, #hearing, #hearing aid, #cochlear implant, #bone conduction hearing aid, #auditory rehabilitation, #sensorineural hearing loss, #conductive hearing loss, #ringing in the ears, #noise in the ear, #cannot hear, #difficulty hearing sounds

Hearing loss refers to a condition in which hearing is reduced and it is hard to hear sounds properly. It has many causes, including aging, noise, and otitis media. According to data from the Health Insurance Review and Assessment Service, the number of patients with hearing loss has been steadily increasing. If you feel your hearing is declining, please do not put it down to age; consult an otolaryngology (ENT) specialist to have the exact cause diagnosed.

Hearing loss is not just a symptom of difficulty hearing sounds; it affects overall quality of life, including withdrawal from relationships, depression, and cognitive decline.

If your hearing declines, please do not leave it untreated by blaming 'age'; consult a medical specialist.

Hematopoietic Stem Cell Transplantation (HSCT)

#hematopoietic stem cell transplantation, #bone marrow transplant, #autologous transplant, #allogeneic transplant, #graft-versus-host disease, #blood cancer, #leukemia, #lymphoma, #loose stool, #watery diarrhea, #frequent trips to the bathroom

Hematopoietic stem cell transplantation (HSCT) is a treatment that transplants hematopoietic stem cells, the cells that give rise to white blood cells, red blood cells, and platelets. It was previously known as bone marrow transplantation, but the name changed once it became possible to collect these cells from peripheral blood as well. It is mainly used to treat blood-related malignancies, and both the treatment process and follow-up care afterward are important.

Hip Fracture

#hip fracture, #fall, #femur, #hip bone fracture, #joint replacement, #fracture fixation, #osteoporosis, #fracture in older adults

A hip fracture is the most serious type of fracture that occurs after a fall. The hip joint is the joint where the pelvic bone and the thigh bone (femur) connect. After a fracture, a person cannot bear weight or stand, which makes walking independently difficult, and in older patients it can lead to complications such as pneumonia, pressure sores, and sepsis, so mortality is high. If you have pain in the hip or upper thigh after a fall, please consult an orthopedic specialist right away.
