Suddenly Hay Fever at 40, 50 or 60?

Allergies can appear for the first time in adulthood, say in your mid-40s. Whether it really is hay fever, a doctor or allergist determines. Until then you keep a diary, on paper or in the symptom diary in Sam, where your symptom days and top symptoms show up in a monthly report as a PDF.

Writing symptoms down while they are fresh is the most useful thing you can do before the visit. This text shows what a practice asks and what belongs in your notes.

Can hay fever start for the first time in midlife?

Yes, and it is not unusual. The ACAAI says allergies can develop later in life. As the body ages, the immune system can start to treat a harmless pollen as foreign and mount an allergic response. Triggers can include moving somewhere new, getting a new pet or changing jobs.

The AAAAI notes that around 20% of people with hay fever in the United States developed symptoms after age 20. Your own history matters here. When did it start? In which weeks does it appear, and in which weeks not? Those dates are exactly what a doctor will want.

Hay fever or a cold?

At the start the two are hard to separate. The NHS describes hay fever as an allergic reaction to pollen. It usually appears when the pollen count is high, so symptoms tend to come back in the same weeks each year. A cold comes from a virus and, according to the NHS, usually goes away after 1 to 2 weeks, while hay fever can last for weeks or months.

Dated notes help here. They show the practice in which weeks your nose runs and in which it stays clear. The details of the difference are in our guide to hay fever or a cold. Whether it is hay fever is for the practice to decide.

What the doctor or allergist asks at a first visit

The first appointment usually starts with a long conversation. A specialist wants to understand your pattern before testing. The Allergieinformationsdienst, a German allergy information service, publishes a 20-question checklist for a first allergist visit. It covers questions such as:

• Do you or your family have other allergies, such as asthma or eczema?
• In which months do the symptoms appear, and how exactly do they feel?
• Since when have you had them, and when are you free of them?
• What medicines do you take, and have you tried anything for this?
• Do you have pets, and what are your pillows, duvet and mattress made of?
• Do you work with anything that irritates your nose or airways?

The checklist asks you to bring copies of any past allergy tests. It often helps to prepare ahead, and our checklist for a chronic condition appointment can get you started.

How testing works

After the conversation there is often a suspicion about which substance is behind it. For hay fever, an allergist usually offers a skin prick test. Per the NHS, a small amount of a possible allergen is placed on your skin to see whether it reacts.

The NHS also lists blood tests as an option. Both are done so the specialist can interpret them. This text is general information, not an instruction. Which tests are sensible for you is the specialist's call.

What you record each day before the appointment

Your diary does not need to be neat. One line per day, written the same day, is enough. Keep it short so you actually fill it in on a bad day. This is a good set:

• The date.
• Sneezing, runny nose, blocked nose, itchy or watery eyes: each 0 to 3, where 0 is none, 1 is mild, 2 is moderate and 3 is strong.
• Whether sleep was disturbed: yes or no.
• Whether your day was affected: yes or no.
• Where you were and what you did.
• If you took something for it: what, and since when.
• One sentence about anything that stands out.

Write the good days down too. A practice often asks about symptom-free times, such as holidays, weekends or winter. A day without symptoms is an entry, not a gap.

A line can look like this (invented example): "Thu, 14 May: sneeze 2, runny nose 2, blocked nose 1, eyes 0. Morning walk, one hour. Woke twice with a blocked nose. Day normal. Took nothing."

In Sam you enter sneezing, nose and eye symptoms with a strength rating in the symptom diary, even before a doctor confirms hay fever. Sleep comes from Apple Health, so you do not have to remember your nights.

When a check with a doctor makes sense

A check is worthwhile when symptoms are new or getting worse. If they are new for you, there is no reason to wait another season. You can book now and keep your diary until then.

The NHS says to see a GP if symptoms are getting worse, you also have asthma and it is getting worse, your symptoms affect your sleep and everyday life, you are not sure what is causing them, or treatments from a pharmacist are not working. If you also have a cough, wheeze or shortness of breath, mention that when you book. For sudden, severe breathing trouble, call your local emergency number (112 in the EU, 999 in the UK, 911 in the US).

Log your symptoms until the appointment in Sam

You arrive with a dated record that shows when and how strong the symptoms were, including the good days.

• Sneezing, nose and eye symptoms go into the symptom diary with a strength rating. Instead of a loose paper sheet, date, strength and course sit in one place you can scroll through.
• Sleep comes from Apple Health, so you only enter what you know yourself. You do not have to rebuild your nights from memory.
• Once a doctor confirms hay fever, the hay fever diary also attaches pollen and air quality for your approximate location and brings everything together in a doctor report as a PDF.

Whether it is hay fever is for the practice to say. Sam does not decide that.
