Gastric Bypass

A bariatric surgical procedure, most commonly performed as a Roux-en-Y gastric bypass, in which a small stomach pouch is created and connected directly to the small intestine, bypassing a large portion of the stomach and the first section of the small intestine. It induces weight loss through both restriction of food intake and some degree of malabsorption of calories and nutrients.

Gauze

Loosely woven cotton fabric used for wound dressings, post-extraction haemostatic packing, and various intra-operative purposes. Sterile gauze is supplied in standard sizes (2x2 inch, 4x4 inch). Post-extraction gauze should be replaced when saturated; biting on a fresh gauze pad for 30-60 minutes after dental extraction is the standard haemostatic measure.

General Anaesthesia

A medically induced state of unconsciousness, analgesia, and muscle relaxation achieved through the intravenous and/or inhalational administration of anaesthetic agents, allowing surgery to be performed without the patient experiencing pain or awareness. Patients are intubated and their vital functions monitored continuously throughout the procedure by an anaesthesiologist.

UK patients considering treatment abroad can use the GMC's Specialist and GP Register at gmc-uk.org to verify whether a returning surgeon is recognised in the UK system.

Graft Crusting

The formation of small scabs or crusts around hair transplant grafts in the recipient area during the first one to two weeks following surgery, as the tiny wounds heal. Gentle washing with saline or diluted shampoo is recommended to keep the area clean and encourage natural crust separation without dislodging the grafts.

Graft Survival Rate

The percentage of transplanted hair follicles that successfully establish a blood supply in the recipient area and continue to produce hair after a transplant procedure. Graft survival rates above 90% are considered favourable and are influenced by factors including extraction technique, out-of-body time, hydration, and implantation skill.

Gum Graft

A periodontal surgical procedure that transplants tissue (most commonly from the palate or a tissue bank) to areas of receded gum or thin gum tissue around the teeth. Indicated for sensitivity, cosmetic recession, or to reinforce thin gum before crown/veneer placement. Healing is typically 2-4 weeks with palatal donor-site discomfort the main early symptom.

Gynecomastia

The benign enlargement of glandular breast tissue in males, caused by a hormonal imbalance or certain medications, resulting in a more feminine chest contour. Surgical treatment involves liposuction and/or glandular tissue excision to achieve a flatter, more masculine chest appearance.
