The majority of males with the ALD gene will develop primary adrenal insufficiency, also known as Addison’s disease. Adrenal insufficiency is when the adrenal glands do not produce enough of an essential hormone called cortisol. If it is going to happen, it usually develops before the legs are significantly affected. It is unusual for men with AMN to develop adrenal insufficiency once they have spastic paraparesis in the legs.
Symptoms include chronic fatigue, lethargy, muscle weakness, weight loss, and difficulty recovering from normally mild infectious illnesses. Affected people often become ‘bronzed’, i.e. progressively darker skinned, sometimes with darker than normal creases on the palms of the hands.
With adrenal insufficiency you can become extremely unwell very quickly if you get a viral or bacterial infection. A minor viral infection may result in severe vomiting which can lead to dehydration and potentially dangerous changes in blood salts. This can also happen if you get very stressed, for example by unusually heavy exercise. If untreated, adrenal insufficiency can lead to a life-threatening condition called ‘adrenal crisis’.
Adrenal insufficiency is easily treated by taking steroid tablets (hydrocortisone with or without fludrocortisone) to replace the missing hormones.
If you are diagnosed with adrenal insufficiency you should be given a kit containing an emergency hydrocortisone injection. Your partner, friend or relative will be trained to give you the injection if you are not retaining your hydrocortisone due to vomiting or diarrhoea.
It’s important that people with adrenal insufficiency are identified immediately if they come into contact with medical services. Your endocrinologist should give you a letter to show at Accident and Emergency so that you get seen immediately if you need to visit.
It’s also advisable to inform your local ambulance service, so that they are aware that you need to be prioritised if you call 999 – ask your endocrinologist or GP how this works in your area. Most ambulance services carry the correct medication. If not, they can administer your own emergency injection as long as it’s in its original box with the directions clearly shown.
You should also wear a medical identity bracelet or necklace saying that you have adrenal insufficiency. That way, if something happens while you are alone the medical services will be alerted to your condition and be able to treat you properly. You can buy these online – just search for ‘medical ID jewellery’.
The Addison’s Disease Self Help Group is an excellent organisation with medically checked information on managing the condition. You can also find out more about the condition on our Addison’s Disease page.
