Adrenal Insufficiency

Lymphoma Treatment - Side Effects

As a result of the steroid chemotherapy that Ryan has been on for his Lymphoma treatment, he has developed Adrenal Insufficiency. This is hopefully a temporary condition that will improve once chemotherapy treatment has finished, however, only time will tell.
There are two types of Adrenal Insufficiency. Primary and Secondary.

Ryan’s type is secondary and can be traced to a lack of ACTH, a hormone which causes a drop in the adrenal glands production of cortisol but not aldosterone. This form of secondary adrenal insufficiency has occurred after receiving a glucocorticoid hormone, in Ryan's case, Dexamethasone steroid as part of his cancer treatment.
Cortisol is normally produced by the adrenal glands, which are located just above the kidneys. Cortisol has many functions, but its most important job is to help the body respond to stress. The high dosage use of Dexamethasone to treat Ryan's lymphoma has caused a hormonal imbalance which hopefully will rectify itself as Ryan’s body begins the healing process once treatment finishes.


Some sources advise that the body needs approximately one month of healing for every month of treatment it received for cancer. Ryan had two months of Radiotherapy and 6 months of Chemotherapy so we are looking at 8-12 months of post-treatment healing, but the doctors have already forewarned us that Ryan faces 2-3 years of maintenance ahead.

The symptoms of adrenal insufficiency usually begin gradually. Chronic, worsening fatigue and muscle weakness, loss of appetite, and weight loss are characteristic of the disease. Nausea, vomiting, and diarrhoea occur in about 50% of cases. However many if not all of these are also common in Cancer and we had put Ryan's symptoms down to chemotherapy side effects.

A random blood monitoring test done in the hospital because Ryan was vomiting despite anti-sickness medication showed severe Hypoglycemia, (or low blood sugar) which warranted further tests that discovered the adrenal diagnosis.

Because the symptoms progress slowly, they are usually ignored until a stressful event like an illness or an accident causes them to become worse. This is called an adrenal crisis, or acute adrenal insufficiency. In most patients, symptoms are severe enough to seek medical treatment before a crisis occurs. However, in about 25% of patients, symptoms first appear during an adrenal crisis which is what happened in Ryan’s case.

Symptoms of an adrenal crisis include sudden penetrating pain in the lower back, abdomen, or legs; severe vomiting and diarrhoea, followed by dehydration; low blood pressure; and loss of consciousness. Left untreated, an adrenal crisis can be fatal.


Ryan was diagnosed by an ACTH Stimulation Test. In this test, blood and/or urine cortisol levels are measured before and after a synthetic form of ACTH is given by injection. In the so-called short, or rapid, ACTH test, cortisol measurement in the blood is repeated 30 to 60 minutes after an intravenous ACTH injection. The normal response after an injection of ACTH is a rise in blood and urine cortisol levels. Patients with either form of adrenal insufficiency respond poorly or do not respond at all. In Ryan’s case, he responded poorly.
Ryan is being treated now with hydrocortisone tablets three times a day and we have been trained in using an injection crisis kit in the case of any future adrenal crisis. He has to carry a steroid alert card at all times and during any time of illness or infection, he is required to double his normal daily dose of tablets called a stress dose, for the duration of the illness or infection.

Adrenal Crisis

We, fortunately, have not yet had to use the crisis injection, but we have been required to up his dose during a recent 10-day hospital stay between chemotherapy cycles, for a staphylococcus infection.

I can never thank the doctor at the Teenage Cancer Trust Unit in Cardiff Hospital for trusting her gut that day and requesting a random blood monitoring test be done. Up until this point, I had assumed his constant vomiting was down to the effects of chemo, but the doctor disagreed as he was on 2 different types of anti-sickness medication. She had a hunch. She saved Ryan’s life.


  1. Emotionally moving stuff - particularly the last sentence.

    1. She did. I hugged her and made her cry, when I thanked her. Mr Darwish the surgeon that saved Ryan's life even more urgently that night his stomach ruptured, will forever be my hero. He gave Ryan just 48 hours. Scary stuff.

  2. I would like to talk to you more my husband has the same disease as Ryan. We live in bristol

    1. Thank you so much for getting in contact Jane. Feel free to email me at or Facebook messenger as Sarah Skilton. I would be happy to be in contact with you Jane. x

  3. I am so pity on Ryan.. very informative post.

Missing Education due to Illness

The Importance of Attendance If you read any news articles on education, correspondence from your child’s school, or are simply clued up on parenting then you will know the importance of school attendance. Schools place a great deal of focus on targets and will often offer incentives and competitions to encourage and increase attendance figures, but what if your child has a serious illness. What happens if they really are not well enough to attend school. What happens then? Attendance targets at Ryan's school are currently set at 95% attendance for the school year. Therefore realistically your child can only miss 10 school days due to illness. Medical appointments such as GP or Dentist do not count, but you are encouraged to make these appointments outside of the school day where feasibly possible. If your child consistently misses school, even if it is only one day a week, that equates to 39 days over the school year. Even missing one day in a week results in pressure on the

Questions to ask after Cancer diagnosis

Cancer Sucks I have shared with you Ryan's lymphoma journey where we have talked about the ups, the downs, the protocols for drugs, the side effects, but I realised recently I have never shared the questions. This post is all about what to ask when you receive a diagnosis of cancer. Receiving a cancer diagnosis is never ever going to be seen as good news. It can never be dressed up or made pretty. It is devastating, it is gut-wrenching, it is life-changing. There is so much information to process you will not think of the questions you need to ask or you will have hundreds of questions you want to ask all at once. These are just some of the questions you can ask once you have processed the news, in order to gain a better understanding of your fight ahead. General Information What type of cancer do I have? Where is it located? What are the risk factors for this disease? Is this type of cancer caused by genetic factors? Are other members of my family at risk? What lifestyle c

Worrying About the Future

  Worrying About the Future. Ryan said to me recently. "Childhood gave me Autism. My teens gave me cancer. What will adulthood bring?" Big worries for someone so young. So much pressure and conditioning are placed upon us about the importance of education and the set path that the majority of us will take through the system to university and/or the job market. What happens if you do not follow that path or miss so much education that the path is no longer open to you. How do you plan for the future? What options are there available to you? Ryan was excluded from his primary school in year 2 and I home schooled him for a year while we worked with the Educational Psychologist to find a placement that would suit his complex needs at the time. Due to his speech, language and communication difficulties the decision was made to withdraw him from Welsh-medium education and focus on English only which meant our choices were limited in the area of Wales that we call home. We

Chemotherapy Cycle 5

What is Normal? With this being our penultimate cycle of chemotherapy I have had several family and friends comment to me “oh I bet you can't wait to get back to normal”. This has really thrown and upset me because it seems to come across that they have failed to comprehend the fact that we have 2-3 years of maintenance ahead and at least two more general anaesthetic surgeries. Not to mention physiotherapy as it is expected Ryan will take 12+ months to heal from the effects of being poisoned from the inside out. Normal is long way off yet. While everyone else appears to all be getting excited that Ryan is coming to an end of his chemotherapy protocol treatment, Ryan himself is becoming more and more tired with the cumulative effect of the onslaught of the chemotherapy drugs and is spending long periods of time in hospital after each cycle with infections due to his impaired immune system now as a result. Ryan is far from excited. Ryan is exhausted. We still have one more cycle t

Cancer Survivor Story

Cancer Doesn’t End When Chemo Does Ryan finished his chemotherapy treatment on his brother's 18th birthday in May 2017. The last two years and eight months were a blur of stress. Yet coming to the end of treatment coincided perfectly with Cancer Survivors Day on the first Sunday in June, each year, so what better way to mark this day than with our own survivor story. Ryan's weight at diagnosis was a staggeringly poor 42kg. He had lost so much weight not being physically able to eat due to the tumour in his throat, but with thanks to his own determination and the feeding tube that he had. Ryan's weight as we start his final chemo cycle....drum roll....prepare yourselves.... was an amazing 57kg. A year on in 2018 and despite going through treatment for the second time after relapse. Ryan weighs an impressive 65kg. Chemotherapy Cycle six Started on Monday, 1 May 2017 for hydration and the week went well without any drama. His final chemo took place on Friday, 5 May wh
