Seven Years on Water and Oats to Stay Alive
Imagine being afraid to eat anything, knowing that even one small bite of the wrong food could seriously harm you or even take your life. For Caroline Cray, this is not an exaggeration. Because of a rare immune disorder, she survives only on water, oats, and baby formula, a diet so restrictive that any deviation could trigger a life-threatening reaction.
This extreme water, oats, baby formula diet is not a choice or trend. It is a medical necessity driven by a serious condition called Mast Cell Activation Syndrome (MCAS).
A Normal Childhood, Marked by Early Allergies
Caroline’s health challenges began early in life. As a toddler, she was diagnosed with a nut allergy. Over the years, she also reacted to foods like kiwi, sesame, and mustard.
However, despite these allergies, she was still able to eat most foods and lead a relatively normal childhood and teenage life. At that stage, food restrictions did not dominate her daily routine.
A Sudden Collapse at College Changed Everything
Things took a dramatic turn in 2017, shortly after Caroline started college. During her first week, she ate chocolate chip ice cream with friends, something she had done many times before. Within minutes, she went into anaphylaxis, a severe allergic reaction that can stop breathing and cause sudden collapse.
Doctors struggled to identify the trigger. Some suspected emotional stress, while others believed cross-contact from nuts might have played a role. Despite extensive testing, no clear cause emerged, leaving Caroline and her doctors searching for answers.
When Doctors Couldn’t Find Safe Food
After weeks in hospital, doctors tested food after food to see what her body could tolerate. The results were alarming.
At one point, only oats, eggs, bacon, and water appeared safe. Even then, reactions were unpredictable. When she returned to university, her symptoms worsened rather than improved.
Eventually, specialists diagnosed her with Mast Cell Activation Syndrome (MCAS), a rare and complex immune disorder.
What Is Mast Cell Activation Syndrome?
In MCAS, immune cells known as mast cells release excessive chemicals without a clear trigger. These chemicals can cause reactions that resemble severe allergies.
Symptoms may include:
- Abdominal pain and diarrhoea
- Breathing difficulty
- Extreme fatigue
- Brain fog
- Suddenly, life-threatening anaphylaxis
Importantly, there is no permanent cure for MCAS. Treatment focuses on symptom control and strict avoidance of triggers, especially food.
A Brief Improvement, Followed by a Medical Emergency
With medication, Caroline experienced a short period of improvement. She managed to slightly widen her diet and even eat outside occasionally. Encouraged, she travelled to the Caribbean.
Unfortunately, after just two bites of salad, she became critically ill. The reaction was so severe that she had to be airlifted back home for emergency care. This incident confirmed how dangerous food exposure remained for her.
Severe Weight Loss and a Critical Medical Solution
Due to her extreme dietary limitations, Caroline’s weight dropped sharply. At 5 feet 8 inches tall, she weighed only 105 pounds, raising serious concerns about malnutrition.
Doctors then introduced a hypoallergenic, amino-acid-based baby formula. This specialised formula provides essential nutrients while minimising the risk of immune reactions.
For Caroline, this formula became a lifeline.
Life Today: Surviving on Water, Oats, and Baby Formula
Seven years later, Caroline still relies exclusively on water, oats, and baby formula to stay alive. This water, oats, and baby formula diet is carefully monitored and medically supervised, as even minor changes could be fatal.
Today, she shares her experience online to raise awareness about MCAS and the realities of living with severe food-related immune disorders. Her story highlights how rare conditions can dramatically alter everyday life and why early recognition and specialised care matter.
Conclusion
Caroline’s journey brings attention to:
- Rare immune disorders that are often misunderstood
- The seriousness of food-triggered anaphylaxis
- The emotional and physical burden of extreme dietary restriction
Most importantly, it reminds us that food, something many take for granted, can be a daily medical risk for some.
As awareness grows, stories like hers may help others get faster diagnoses, better support, and safer care options, especially for conditions as complex as MCAS.
