Key Takeaways

A diagnosis of paroxysmal nocturnal hemoglobinuria (PNH) can feel overwhelming for teens and young adults, but with the right treatment and care, most people with PNH can get back to living a fairly normal life.
Tracking your symptoms and triggers in a diary or app can help you and your doctor spot patterns and manage your condition more effectively. Sticking to your treatment plan is also important because it is linked to better outcomes and a longer lifespan for people living with chronic conditions.
If you are a student or employee living with PNH, you have the right to ask for accommodations to help you succeed, and connecting with a support group can also help you find comfort and coping strategies, so reaching out to your healthcare team is a great first step toward getting the support you need.

A diagnosis of paroxysmal nocturnal hemoglobinuria (PNH) can be life-altering at any age. For someone in their teens or 20s, it can throw plans for school, your social life, and the future into question as you navigate this new reality.

The good news is that with the right treatment and care, life can get back to being fairly normal for most people with PNH. But it’s vital to learn as much as you can about your condition to know how best to manage your health.

One member of myPNHteam who was diagnosed at age 16 shared some advice for teens and young adults newly diagnosed with PNH.

“Remember that your health comes first,” they said. “Once you begin treatment, you’ll know how to find the balance between your fatigue and your ability to work so that it minimally impacts your quality of life.”

Here’s what you need to know if you’re in your teens or 20s and newly diagnosed with PNH. That includes how and why to track symptoms and triggers, why it’s important to stick to your treatment plan, and potential complications to watch for.

We’ll also cover why lifestyle choices matter for your long-term health, and what to know about your right to workplace and school accommodations.

Track Your Symptoms and Triggers

In people with PNH, the immune system mistakenly attacks red blood cells and platelets (blood cell fragments involved in clotting). Symptoms of this rare disease vary from person to person, but some important ones are dark urine that’s most apparent in the morning and severe fatigue.

Other common symptoms, which may be mild or severe, include:

Difficulty swallowing
Spasms in the esophagus (the tube in your throat that carries food to your stomach)
Pain in your stomach, chest, or back
Shortness of breath
Erectile dysfunction (difficulty achieving or maintaining an erection)

Symptoms can flare periodically in people with PNH. Tracking symptoms of PNH and triggers that make your symptoms worse can help you and your PNH specialist spot patterns and better manage your condition.

It’s helpful to keep a symptom and trigger diary. Triggers of PNH can be anything that makes your symptoms worse. Common triggers include:

Infections
Surgery
Injury
Physical or emotional stress

Find a way to track symptoms that works for you, whether via a health tracking app or a journal you write in. Share it with your doctor during office visits. This can help them determine if your medication should be adjusted to help prevent PNH episodes.

Stick to Your Treatment Plan

It can be hard to stick to a treatment schedule, especially if you’re on the go with school, work, and plans with friends or partners. Every day may look different, and it’s hard to stay on track with taking medications.

However, finding ways to stick to your PNH treatment is essential to feel your best with PNH and keep that busy lifestyle going.

Maintaining treatment properly is associated with better outcomes and longer lifespan in people living with chronic diseases.

Here are a few challenges people run into that make it hard to stick with treatment:

Trouble accessing medication
Having a complicated regimen that you find hard to follow
Being forgetful due to stress or fatigue
Believing that medication may not be effective
Worrying that you may become dependent on a medication

If you have difficulty sticking to your treatment, or if you don’t think it’s working well for you, it’s important to talk openly with your doctor before making any changes in your treatment plan.

Your healthcare team can work with you to address any issues that are getting in the way of you taking medication as prescribed.

There are now more treatments than ever for PNH, so you have options.

Avoiding Complications of PNH

Without appropriate treatment, PNH can lead to life-threatening complications such as:

Chronic kidney disease
Blood clots
Bone marrow failure, where your bone marrow can’t produce enough blood cells
Infectious diseases
Pulmonary hypertension (high blood pressure in the arteries that carry blood to the lungs)

Treating PNH can help prevent complications and give you a better outlook.

Good communication with your doctor can help ensure that your treatment is as effective as possible and that you get the support you need to stick with your treatment.

Take Precautions in Certain Situations

There are a few situations in which you may need to take special precautions to avoid extra problems with PNH.

Here are some situations you should be aware of and discuss with your doctor.

Higher Altitudes and Travel by Air

With air travel and high altitudes, there’s less oxygen. This may cause chest pain. Changes in cabin pressure can also cause bleeding in people with low platelet counts.

You’re also more susceptible to viral infections due to air recirculating in the airplane cabin. Drinking water and walking around while flying can help reduce some of the risks.

Be sure to talk to your healthcare team before flying. Your doctor may recommend blood thinners for long flights.

Pregnancy

Although it’s possible to have a healthy pregnancy with PNH, you have an increased risk of blood clots and may need more blood transfusions while pregnant.

Before and during pregnancy, it’s essential to coordinate your care with an obstetrician who’s familiar with PNH and high-risk pregnancies, along with your PNH specialist. They can work together to monitor your condition and treatment plan.

Surgery

Surgery can also increase the risk of blood clots and bleeding. Your surgeon and PNH specialist should work together to determine if you may need a blood transfusion prior to surgery. They can also review your treatment plan to see if surgery will impact any aspect of your treatment.

Stay Up To Date on Vaccinations

You can help prevent serious infections by following recommended vaccination schedules. Your doctor can advise you on vaccines that you should be getting. Preventing infection can protect your health and help you manage your condition more effectively.

Make Healthy Lifestyle Choices

A healthy diet, regular exercise and physical activity, and self-care can help protect your health and well-being. For people with PNH, a healthy lifestyle might look like:

Planning well-balanced meals — A diet rich in vegetables and fruits is important. Avoid processed foods or beverages, added sugar, and refined white flour products.
Drinking plenty of water — Staying hydrated can help prevent blood clots.
Getting regular exercise — Keeping active can help improve your physical and mental well-being.
Getting enough sleep — Avoid sleeping during the day, even if you feel fatigued. This can make sleeping at night more difficult.
Managing stress — Self-care such as meditation, a warm bath, or taking time to read and unwind can help you manage stress.

If you need help with diet, exercise, or stress management, reach out to your healthcare team.

Look Into Workplace or School Accommodations

If you’re a student, you may need help keeping up with your school workload due to the challenges of PNH. You can talk to administrators about special accommodations to help you succeed.

School accommodations are legally mandated for students with serious health issues that may limit their physical or psychological abilities, and may include provisions such as:

Adjusted class or test schedules

Special parking permits

Modified physical education

Likewise, workplace accommodations are also mandated by law and require employers to help make the workplace easier for people with chronic illnesses that cause disability. Depending on your particular condition, workplace accommodations may include:

Modifying work schedules for medical needs

Adjusting the physical demands of a job

Changing job responsibilities

You may be eligible for government Social Security Disability Insurance (SSDI) if the condition limits or prevents you from working. SSDI provides monthly payments to people with disabilities who qualify.

Reach Out for the Support You Need

Getting support from others who know what you’re going through can help you develop good coping strategies for the physical and emotional challenges that come with PNH. An in-person or online support group can provide comfort, tips, and resources.

One member of myPNHteam wrote about the support they find in the community. “With so many questions around symptoms, lifestyle, and the latest in research, you’re in the right place — this community is full of people who really get it,” they said.

There’s no doubt that PNH can be challenging for young adults, and many young people with PNH may need to adjust some of their life goals. At the same time, with careful management of your condition, a good support system, and some perseverance, you can have a fulfilling and productive life with PNH.

“I’ll be returning to work after a period of seven months,” another member shared. “Everything will feel new, and I know that life has changed a bit, but I’m confident that everything will be fine.”
