Autonomic & Neurovascular Medicine

The Autonomic & Neurovascular Medicine Unit at St John & St Elizabeth Hopsital provides a highly specialised diagnostic service for a wide variety of autonomic disorders: postural tachycardia syndrome, syncope, orthostatic intolerance, postural hypotension, hyperhidrosis and much more.

Autonomic investigations play a key role in aiding the doctors in the diagnosis of autonomic disorders and are also important in tailoring an individual treatment and management plan.

Our Autonomic & Neurovascular Medicine Consultants

Autonomics

The autonomic nervous system (ANS) is comprised of the sympathetic (fight or flight response) and parasympathetic (rest and digestion) nervous systems. The ANS innervates every end organ in the body: such as skin, heart,  bladder and bowels;  and is very important in the control of bodily functions, such as regulation of sweating, blood pressure, heart rate, digestion and sexual function.  Individuals with autonomic disorders may have many disabling symptoms, such as lightheadedness or fainting, constipation, bladder control problems, and sexual dysfunction.

The Autonomic & Neurovascular Medicine Unit provides a highly specialised diagnostic service for a wide variety of autonomic disorders. We have two state of the art laboratories incorporating the latest advances in non-invasive technology. Autonomic investigations play a key role in aiding the doctors in the diagnosis of autonomic disorders and are also important in tailoring an individual treatment and management plan. The team aim to help people with autonomic symptoms, some of which are multiple and complex, to successfully manage their daily lives.

Autonomic dysfunction is usually a multi-system disorder and we work closely with other departments within St John & St Elizabeth Hospital and other leading consultants: including Hypermobility Unit, Cardiology, Imaging, Physiotherapy, Gastroenterology, Urology, Gynaecology and Immunology.

Make an enquiry

If you have any questions relating to treatment options or pricing information, get in touch with us by filling out one of our contact boxes or giving us a call on +44 207 806 4060.

Our Appointments Team have a dedicated and caring approach to finding you the earliest appointment possible with the best specialist.

If you are self-paying you don’t need a referral from your GP for a consultation. You can simply refer yourself* and book an appointment.

If you have health insurance (e.g. Bupa, Axa Health, Aviva), you will need to contact your insurer to get authorisation before any treatment, and in most cases you will also require a referral letter from your GP.

If you are not registered with a GP, we have an in-house private GP practice you can use. Alternatively, we can suggest the most appropriate course of action for you to take, given your location and individual circumstances.

*Please note – for investigations such as X-rays and MRIs, a referral will be required. However, we may be able to arrange this for you through our on-site private GP.
