GAD

Generalised anxiety disorder (GAD) is a long-term condition that causes anxiety about a wide range of situations and issues, rather than one specific event.

Disproportionate, pervasive, uncontrollable, and widespread worry leads to a range of somatic, cognitive, and behavioural symptoms (Hoge, Ivkovic and Fricchione, 2012; NICE CKS).

Other anxiety disorders include PTSD and OCD.

GCA

Giant cell arteritis (GCA) is a vasculitis of arteries, typically those in the head and neck. 

GCA is a medical emergency.

Symptoms typically include headache, severe pain and tenderness over the temples (hence GCA is also called temporal arteritis) and the scalp, jaw pain while eating (jaw claudication), and flu-like symptoms. 

Visual disturbance (double vision or visual loss) and jaw claudication demands urgent medical attention, with high-dose steroid as management.

GCA is frequently associated with PMR.

GCS

The Glasgow Coma Scale (GCS) is a neurological scale which aims to give a reliable and objective way of recording the state of a person's consciousness for initial as well as subsequent assessment. A person is assessed against the criteria of the scale, and the resulting points give a person's score between 3 (indicating deep unconsciousness) and either 14 (original scale) or 15 (more widely used, modified or revised scale).

GDM

Gestational diabetes mellitus (GDM) is diabetes (high blood glucose) that develops during pregnancy. GDM is usually diagnosed from a blood test 24 to 28 weeks into pregnancy. Women with GDM don’t have diabetes before their pregnancy, and it usually goes away after giving birth.

In the UK, roughly 16 out of every 100 women will develop GDM.

The most common problem associated with GDM is a large baby (macrosomia), which can make vaginal delivery more difficult and may mean caesarean section is required.
