PIP for Addison's Disease - Can You Claim? Guide 2026

Addison's disease (adrenal insufficiency) is serious and lifelong. The fatigue, dizziness, muscle weakness and risk of adrenal crisis all affect PIP activities significantly. Despite being potentially life-threatening, many claimants struggle because symptoms are invisible.

Which Activities Does Addison's Affect?

Preparing Food (Activity 1) – Extreme fatigue and dizziness making it unsafe to stand at a cooker. Muscle weakness affecting ability to lift pots. Nausea reducing ability to handle food.

Taking Nutrition (Activity 2) – Nausea, loss of appetite, salt cravings. Skipping meals can trigger crisis. If someone must remind you to eat, this scores.

Managing Therapy (Activity 3) – Hydrocortisone at precise times (2-3 daily), sick day rules (doubling doses during illness) and the emergency injection kit are all medication in PIP terms. If you need someone to prompt or check your doses, work out the sick day dose with you or give the injection, that is descriptor b, worth 1 point however many medicines are involved. Endocrinology appointments and blood tests do not count. The therapy descriptors worth 2 to 8 points only cover prescribed non-drug treatment done at home that another person has to supervise, prompt or help with, so they rarely apply to Addison's. The emergency injection requiring someone else to administer it if you collapse is supervision for safety – it carries weight under the reliability test and the other activities rather than as therapy hours.

Washing and Bathing (Activity 4) – Dizziness and weakness in hot water. Risk of collapse in the shower. Fatigue making personal care difficult without resting.

Planning and Following Journeys (Activity 11) – Fear of adrenal crisis away from home. Need someone nearby who knows how to use the emergency injection. Dizziness making navigation difficult.

Moving Around (Activity 12) – Muscle weakness and fatigue limiting walking distance. Dizziness and unsteadiness increasing falls risk.

Adrenal Crisis and PIP

The risk of adrenal crisis is your strongest argument. It is a medical emergency that can be fatal. You need someone to recognise signs and administer emergency injection. This means supervision for safety at all times.

What Evidence Helps?

• Endocrinologist letters
• Emergency injection prescription
• Medical alert card/bracelet
• Hospital records for any crises
• Steroid sick day rules documentation
• Carer statement

Sick Day Rules and Activity 3

The Addison's Sick Day Rules are a structured medication adjustment protocol. The rules require you to double or triple your hydrocortisone dose during illness, injury, dental procedures, vomiting, severe stress or surgery and to administer an IM hydrocortisone injection if you cannot keep oral medication down. The time and cognitive burden of:

• Recognising when sick day rules apply (fever, vomiting, infection, dental work)
• Calculating the correct increased dose (typically double for moderate illness, triple for severe)
• Tapering back down safely once well
• Carrying and rotating emergency injection kit (hydrocortisone 100mg, syringes, needles)
• Training family members in injection technique
• Wearing medical ID and carrying steroid emergency cards
• Monthly NHS reviews if newly diagnosed, every 6-12 months once stable
• Daily medication itself - typically 2-3 split doses at exact times

Be clear about how this scores. Since March 2017 the regulations exclude taking or administering medication and monitoring a health condition from the definition of therapy, so none of this counts towards the weekly hours in descriptors c to f, and appointments and reviews do not count at all. Needing someone to prompt or check your doses, work out the sick day dose with you, keep the emergency kit in date or give the injection scores Activity 3 descriptor b, 1 point, however long it takes. The list above is still worth writing out in full: it is evidence that you cannot manage the condition safely without another person, which feeds the reliability test in regulation 4(2A) and the supervision arguments under Activities 1, 4 and 11.

Secondary Adrenal Insufficiency - Equally Serious

Many PIP claimants with adrenal insufficiency have secondary adrenal insufficiency (caused by long-term steroid use for asthma, IBD, rheumatoid arthritis, transplant immunosuppression or pituitary problems) rather than classic primary Addison's. The functional impact is similar - same adrenal crisis risk, same sick day rules, same hydrocortisone replacement. Make sure your form names your specific diagnosis and the cause.

The Symptom Picture Most Assessors Miss

Even on optimal replacement, many people with Addison's have ongoing symptoms:

• Fatigue. Cortisol replacement does not perfectly mimic natural circadian cortisol release. Many patients have persistent fatigue, especially mid-morning before second dose and mid-afternoon.
• Muscle weakness and aches. Particularly in lower limbs, affecting walking distance and standing tolerance.
• Postural hypotension. Dizziness on standing, fainting episodes, falls risk - relevant to Activities 4 (washing safely) and 12 (mobility).
• Cognitive issues. "Brain fog," poor concentration, slow processing - relevant to Activities 8 and 10.
• Mood changes. Depression, anxiety, irritability - relevant to Activity 9.
• Heat intolerance. Many cannot manage hot environments, including showers and summer outdoors.
• Cold intolerance. Need extra layers, struggle in winter.
• Salt cravings and weight changes. Reflect imperfect aldosterone replacement.

Frequently Asked Questions

I'm "stable" on hydrocortisone. Can I still claim?

Yes. "Stable" means you haven't had a crisis recently - it doesn't mean you're well. The medication regime itself is complex, you still experience fatigue and weakness, and the risk of crisis NEVER goes away. The emergency injection kit you carry at all times is proof that you need supervision for safety.

Does carrying an emergency injection count as therapy?

No. The emergency hydrocortisone injection is medication, not therapy, and since March 2017 the regulations exclude administering medication from the therapy descriptors. What it shows is that you need another person to be able to manage your medication when you collapse or cannot keep tablets down, which is Activity 3 descriptor b (1 point). It is also strong evidence that you need supervision for safety, which matters under the reliability test and Activities 1, 4 and 11. Carrying the kit, knowing the sick day rules and training others to inject you all belong on the form for that reason.

I have never had an adrenal crisis - does that weaken my claim?

No - it actually shows your management is working. The relevant point is the RISK of crisis, not the history. Crisis can happen at any time given the right trigger (infection, injury, missed dose). The supervision and monitoring required to prevent crisis is what scores.

How do I describe Addison's to an assessor who has never heard of it?

Use this script: "Addison's disease means my adrenal glands do not produce cortisol. Cortisol is essential for life - without my daily medication I would die within days. During any illness, injury or stress my body cannot produce the extra cortisol it needs and I can go into adrenal crisis, which is potentially fatal. I carry an emergency injection and a medical alert because if I collapse or vomit my medication I need someone to inject me with hydrocortisone urgently."

I am on Plenadren or hydrocortisone subcutaneous infusion - is that different?

Modified-release hydrocortisone (Plenadren) and continuous subcutaneous infusion are advanced treatments for difficult-to-control Addison's. These suggest your condition is severe enough that standard treatment is inadequate. Include letters from your endocrinologist about why standard hydrocortisone did not work for you.

What about Addisonian crises requiring hospital admission?

Any hospital admission for adrenal crisis is powerful evidence. Submit the discharge letter with your PIP form. Each crisis shows the real-world consequences of your condition and supports an enhanced rate claim.

Will the DWP automatically award me PIP because Addison's is serious?

No. No condition is automatic for PIP (except SR1 for terminal illness). You must describe functional impact on each of the 12 activities. The good news is that Addison's has clear, well-defined PIP-relevant impact - Activities 3, 4, 11 and 12 in particular - so a properly completed form usually qualifies for standard or enhanced daily living.
