Six hundred thousand undiagnosed, their symptoms dismissed as stress
In Portugal, a million people carry a condition that governs their energy, mood, weight, and heart — yet six hundred thousand of them have never been told. On World Thyroid Day, patient advocates placed a formal demand before the health minister and parliament: that hypothyroidism and hyperthyroidism be recognized not as minor inconveniences, but as the chronic, lifelong diseases they are. The ask is practical as much as symbolic — faster medication access, better insurance, structured monitoring — and it echoes a recognition that countries like England have already extended to their citizens. The deeper question Portugal must now answer is whether a health system can afford, in any sense, to keep treating a treatable condition as invisible.
- Six hundred thousand Portuguese citizens are living with undiagnosed thyroid disease, their symptoms quietly mistaken for stress, aging, or the ordinary weight of modern life.
- By the time many patients receive a diagnosis, multiple organs have already been affected — the disease progressing further than it ever needed to.
- Patient advocates delivered an open letter to the health minister demanding official chronic disease classification, arguing that without it, patients are left to navigate lifelong conditions without structural support.
- Endocrinologists acknowledge the late-diagnosis crisis but remain divided on whether a national screening program is warranted, calling instead for greater clinical vigilance.
- England already grants hypothyroid patients free prescriptions through chronic disease exemption certificates — a concrete model Portugal has yet to adopt.
- While the government deliberates, the Thyroid Disease Association is offering free screenings at a shopping center in Amadora, a small but visible act in a very large gap.
A million Portuguese citizens live with thyroid disease, but the majority — some six hundred thousand — have no idea. Their fatigue, mood swings, weight changes, and hair loss get attributed to stress or age, while the small gland regulating nearly every system in the body continues to malfunction in silence. The damage accumulates quietly, and by the time a diagnosis arrives, it often comes too late.
On World Thyroid Day, the Thyroid Disease Association, led by Celeste Campinho, delivered an open letter to the health minister and parliament's health committee calling for hypothyroidism and hyperthyroidism to be officially classified as chronic diseases. The demand is not ceremonial. These are lifelong conditions requiring continuous medication, regular monitoring, and clinical oversight — yet Portugal's health system currently treats them as minor ailments, offering patients little structural support.
The diagnostic problem runs deep. Thyroid symptoms overlap so thoroughly with other conditions — depression, heart irregularities, gynecological issues — that patients are often routed to the wrong specialists, none of whom think to check thyroid function. Paula Freitas, president of the Portuguese Society of Endocrinology, confirms that diagnoses arrive late, when patients are already significantly ill, with consequences for mental health, fertility, pregnancy, and cardiovascular risk. She stops short of endorsing national screening, but urges clinicians to consider thyroid dysfunction when persistent symptoms appear.
Campinho points to England, where hypothyroid patients can obtain exemption certificates granting free NHS prescriptions — a recognition with real consequences for patient welfare. Official chronic disease status in Portugal would mean faster medication access, better insurance coverage, and more structured follow-up care. It would also likely reduce long-term costs to the national health system by preventing the expensive complications that late diagnosis produces.
In the meantime, the association is holding free screening clinics, including one at a shopping center in Amadora the Monday after World Thyroid Day. It is a modest effort against a large and largely invisible problem — but the association's broader aim is to move government and parliament toward a recognition the evidence already supports: that hundreds of thousands of Portuguese citizens are suffering from a condition that is, with proper care, entirely manageable.
A million Portuguese citizens are living with thyroid disease, but six hundred thousand of them don't know it. They walk around tired, their moods swinging without explanation, their weight creeping up, their hair thinning. They blame stress. They blame age. They blame the pace of modern life. Meanwhile, their thyroid—the gland that regulates metabolism and touches nearly every system in the body—is quietly malfunctioning, and the damage accumulates.
On World Thyroid Day, patient advocates launched an open letter to the health minister and members of parliament's health committee, demanding that hypothyroidism and hyperthyroidism be officially recognized as chronic diseases. The Thyroid Disease Association, led by Celeste Campinho, argues that this is not a symbolic gesture but a practical necessity. These are lifelong conditions that require continuous medication, regular monitoring, and clinical oversight. Yet Portugal's health system treats them as minor ailments, leaving patients to navigate their care without the structural support that chronic disease status would provide.
The problem begins with diagnosis. Symptoms of thyroid dysfunction—fatigue, mood changes, weight gain, constipation, cold intolerance, hair loss, tremors, irregular heartbeat—overlap so thoroughly with other conditions and with the ordinary wear of daily life that both patients and healthcare providers often miss them. A woman experiencing irregular periods might see a gynecologist. A person with a racing heart might visit a cardiologist. A patient complaining of depression might be referred to psychiatry. None of these specialists may think to check thyroid function, even though thyroid disease could be the root cause of everything. By the time diagnosis arrives, organs have already been affected. The disease has progressed further than it needed to.
Paula Freitas, president of the Portuguese Society of Endocrinology, Diabetes and Metabolism, acknowledges this reality. Diagnoses in Portugal come late, she says, when patients are already significantly ill. She notes that thyroid disease can compromise mental health, fertility, pregnancy outcomes, and cardiovascular health when left undiagnosed or poorly controlled. Yet she stops short of endorsing a national screening program, saying consensus among clinicians has not yet formed. What she does advocate is vigilance—healthcare providers should consider thyroid dysfunction when patients present with persistent symptoms, and patients should ask their doctors for routine blood work if something feels wrong.
Campinho pushes further. She points out that in England, patients with hypothyroidism who require treatment can obtain an exemption certificate that grants them free prescriptions through the National Health Service. This recognition of the disease's chronic nature has concrete consequences for patient welfare. Portugal has not adopted such measures. If thyroid diseases were officially classified as chronic, medication could be prescribed more quickly, insurance coverage would improve, and clinical follow-up would be more structured. The cost to the national health system would likely decrease, because early detection and consistent management prevent the expensive complications that arise from late diagnosis.
The association is holding screening clinics as part of its awareness campaign. On the Monday after World Thyroid Day, volunteers will set up at a shopping center in Amadora, starting at nine in the morning, offering free thyroid checks. It is a small gesture in a large gap. A national screening program would be different entirely, Campinho acknowledges, but the association lacks the infrastructure to mount one. What it can do is push the government and parliament to recognize what the evidence shows: that six hundred thousand undiagnosed Portuguese citizens are suffering from a treatable condition, and that official recognition of thyroid disease as chronic would change the trajectory of their care.
Freitas also emphasizes nutrition, the theme chosen for this year's World Thyroid Day. People with thyroid disease should follow a Mediterranean diet, avoid smoking, and be skeptical of internet forums recommending unregulated supplements. Iodine, selenium, iron, and zinc are essential for thyroid function, but they are available in ordinary food—fish, shellfish, salt, Brazil nuts, meat, eggs. Supplementation should only occur under medical supervision after blood tests show deficiency. The message is simple: eat well, stay alert to persistent symptoms, and ask your doctor for thyroid testing if something feels wrong. The gland that controls so much of how we feel and function deserves at least that much attention.

Hypothyroidism is a disease for life, and it is not even contemplated in public health policies. For many people it is a permanent chronic disease with significant impact on quality of life, requiring treatment, clinical monitoring, and follow-up throughout life.— Celeste Campinho, president of the Thyroid Disease Association
In Portugal, diagnoses continue to be made late, when the person is already more ill, practically with all organs affected. If diagnosis is not made in time, the situation can evolve into a more serious case.— Paula Freitas, president of the Portuguese Society of Endocrinology, Diabetes and Metabolism
The Hearth Conversation Another angle on the story
Why does it matter whether thyroid disease is called chronic or not? Isn't it still the same disease either way?
It's the difference between being seen and being invisible. Right now, a patient with hypothyroidism has to fight for faster medication refills, negotiate insurance coverage, and convince doctors that their symptoms are real. If it's officially chronic, those barriers dissolve. The system moves faster. The patient doesn't have to prove themselves.
But you said six hundred thousand people don't even know they have it. How does official recognition help someone who hasn't been diagnosed?
That's the harder problem. Recognition helps the diagnosed patients immediately. But it also signals to the entire healthcare system—to every doctor, every specialist—that this disease matters, that it's worth screening for, that persistent fatigue or mood changes might not be stress. It changes the culture of how the disease is taken seriously.
The article mentions that symptoms look like so many other things. How do you screen for something that mimics depression, or aging, or just being tired?
A simple blood test. That's all it takes. TSH levels tell you everything. The barrier isn't medical—it's awareness. Doctors have to think to order the test. Patients have to think to ask for it. Right now, neither side is thinking about it enough.
England has this exemption certificate system. Could Portugal just copy that?
Campinho says it's not directly transferable, but it proves the concept works elsewhere. It shows that other countries have already decided thyroid disease is chronic enough to warrant special protections. Portugal is behind on that recognition.
What happens to someone who goes undiagnosed for years?
Their organs start to fail. Their mental health deteriorates. Women lose fertility or have repeated miscarriages. Their heart rhythm becomes irregular. By the time they're finally diagnosed, they're much sicker than they needed to be. And the cost to treat them is much higher.
