Hypothyroidism and Health Insurance in Spain in 2026
Hypothyroidism and Health Insurance in Spain, hypothyroidism is a disorder in which the thyroid gland does not produce the proper amount of certain hormones needed by the body. Although this condition is not widely discussed, recent studies show that 9.1% of the Spanish population suffers from hypothyroidism. Therefore, all individuals with this condition require the best health insurance.

Causes of Hypothyroidism
In this paragraph, I will discuss the prominent causes of hypothyroidism in Spain and the thyroid gland’s organic disorder. These alterations can lead to an enlarged goiter. Why does this happen?
- Due to surgical intervention.
- Another cause: an extraction with radioactive iodine or other rare causes in Spain.
Other Causes of Hypothyroidism
- A family member who has had endocrine problems or thyroid goiter.
- Being over 50 years of age.
- Suffering from an autoimmune complication that attacks thyroid cells and their enzymes.
- Having undergone radiation to the neck or head during cancer treatment or hypothyroidism.
- A diet low in or excessive in iodine.
- Removal of part or the entire thyroid gland due to cancer or Graves’ disease.
- A complication during pregnancy where the woman bleeds excessively during pregnancy due to damage to the pituitary gland, an endocrine gland.
Symptoms of Hypothyroidism The lack of thyroid hormones causes the body’s functions to slow down. The symptoms can be subtle and appear gradually; some of these can be mistaken for depression, particularly in older people. Facial expressions become dull. The voice becomes hoarse, and speech slows. The eyelids droop. The eyes and face swell. Hair becomes thin, rough, and dry. Skin becomes rough, scaly, and thick. Many people with hypothyroidism feel tired, gain weight, suffer from constipation, develop muscle cramps, and are unable to tolerate the cold. Their pulse becomes slower, the palms of their hands and soles of their feet may turn a literal orange color, and the outer edges of their eyebrows gradually thin out.
Primary Hypothyroidism In this case, primary hypothyroidism is explained:
- It occurs as a result of thyroid disease.
- It is universally secondary to Hashimoto’s thyroiditis and is often associated with a rigid goiter or a smaller-than-normal fibrous thyroid with limited or no function.
Secondary Hypothyroidism It occurs due to insufficient TSH in the context of inflammatory diseases.
- An uncommon cause could be a vascular contusion and trauma or surgery-related injuries.
Tertiary Hypothyroidism It occurs due to the absence of thyrotropin-releasing hormone (TSH).
- It can also be caused by variations in inflammatory diseases and injuries.
Subclinical Hypothyroidism Subclinical hypothyroidism results from the same alterations as clinical hypothyroidism. The most common cause in populations with adequate iodine intake is autoimmune Hashimoto’s thyroiditis, which is responsible for about 50% of hypothyroidism cases in Spain.
Congenital Hypothyroidism Newborns who cannot produce enough thyroid hormone have hereditary hypothyroidism, meaning they are born without a functioning thyroid gland. In Spain, approximately 1 in every 2,500 to 6,000 babies is born with congenital hypothyroidism. It is twice as common in girls as in boys.
Diagnosis and Treatment of Hypothyroidism and Health Insurance in Spain How is it diagnosed? The only way to know for sure if a patient has hypothyroidism is by performing blood tests, such as:
- TSH testing: This is the most fundamental and sensitive test for diagnosing hypothyroidism. An abnormally high TSH means the patient has hypothyroidism.
How is it treated? This is a chronic condition, treated by replacing the thyroid hormone that the gland can no longer produce. 2. Substitution with T4 can restore thyroid hormone levels in the body. 3. Synthetic levothyroxine tablets contain hormone equal to T4, which the thyroid gland produces.
Recommended Foods for Hypothyroidism Patients and Health Insurance in Spain
- Fatty fish like tuna and salmon rich in omega-3 fatty acids, nuts like hazelnuts and macadamia, which are rich in selenium to help thyroid function. Consume whole grains (brown rice, whole oats, whole wheat bread) to prevent constipation.
- Eat fresh, non-starchy fruits and vegetables to prevent weight gain. Increase consumption of legumes (black and red beans, chickpeas, lentils) when feeling low on energy.
- Increase intake of selenium-rich foods such as red meat, chicken, salmon, tuna, whole unrefined grains, nuts, garlic, and onions.
Foods Not Recommended for Hypothyroidism Patients and Health Insurance in Spain A person with hypothyroidism should avoid:
- Raw cabbage, kale, and radishes.
- Broth, soup, or water from boiling foods. Soy and soy-based products as they increase fecal excretion, as well as the thyroxine hormone, and the necessary means to combat this common disease in Spain.
- If you suffer from hypothyroidism and consume soy-based products, it will be essential to review the levothyroxine hormone dosage with your endocrinologist to improve treatment for hypothyroidism.
Hypothyroidism and Health Insurance in Spain It is said that COVID-19 infection can cause thyroiditis, according to an unexpected study conducted in Italy in recent months.
This case resulted from a viral infection. Many viruses have been associated with hypothyroidism in Spain.
Doctors examined an 18-year-old woman infected with COVID-19 after contracting it from her parent. She fully recovered, testing negative a few days later, but began noticing additional symptoms such as neck and thyroid pain, fever, and increased heart rate. She was transferred back to the clinic, where she was diagnosed with subacute thyroiditis, despite having normal thyroid function just a month earlier. “Due to the chronological association, it can be considered responsible for the onset of subacute thyroiditis.”

Pregnancy Disorders and Hypothyroidism This disorder can exist during or even before women become pregnant, and it may also develop during maternity. Being pregnant does not change thyroid symptoms. The impact on the fetus depends on the type of thyroid disorder and the medications used for treatment.
We can explain that the risks are as follows:
- Regarding an overactive thyroid (hyperthyroidism) if untreated: delayed or reduced growth of the fetus and fetal death.
- With an underactive thyroid (hypothyroidism) untreated: it causes damage to the child’s intellectual development and spontaneous abortion.
Postpartum Thyroid Disorder In the first 6 months following childbirth, the thyroid gland can become underactive (hypothyroidism) or overactive (hyperthyroidism). Postpartum thyroid disorders in Spain are more common among women with goiter.
In some cases, they may have:
- Type 1 diabetes: If women have any of the above risk factors.
- Doctors measure thyroid hormone levels during the course of postpartum thyroid disorders. These tend to be temporary and often require treatment.
- In the first weeks after childbirth, a disturbance known as painless thyroiditis may arise suddenly. This is possibly caused by an autoimmune reaction.
How Hypothyroidism Affects Sexual Desire A lack of sexual desire is one of the first symptoms related to the diagnosis of this disorder. In fact, the lack of sexual desire is one of the most common signs in diagnoses of metabolism-related diseases in general. If you think about it, it makes sense: if your body isn’t functioning as it should and there’s a hormone imbalance, libido tends to decrease more than normal.
Thyroid Cancer and Health Insurance in Spain Thyroid cancer originates in the thyroid gland when cells begin to grow uncontrollably.
Types of Cancer
- Differentiated (including papillary, follicular, and Hurthle cell)
- Medullary
- Anaplastic (an aggressive cancer)
Where Does Thyroid Cancer Start? The thyroid gland is located at the front of the neck, below the thyroid cartilage (the Adam’s apple). It is not visible or palpable in most people. This butterfly-shaped gland has two lobes:
- Right lobe
- Left lobe Both are connected by a narrow piece of gland called the isthmus.
How to Recover from Thyroid Cancer It is possible to regain sexual desire. These thyroid-related disorders, when treated correctly, should not cause major changes in your daily life. With the right treatment, everything gradually gets regulated, and sexual desire returns. Not just libido, but weight and all the physical and physiological changes that have occurred. Clearly, the results are not instantaneous, but it is likely that everything will return to normal, up to 200%. Once hormone levels return to their proper range and the medication is well-regulated, the thyroid will no longer be an issue for maintaining sexual relations.
Hypothyroidism Complications in Dogs Sometimes we are asked whether it’s wise to use thyroid glands from pigs or cattle as a more natural treatment. The answer is simply no. These products do not have proper quality control to ensure a reliable amount of thyroid hormone for our pets with hypothyroidism. Doses may be completely different, depending on their immune systems, so when using such products, it is important to consult a veterinarian for our pets in Spain.
Prevention of Hypothyroidism and Health Insurance in Spain There is currently no known method to prevent hypothyroidism in general. The only prevention that can be done is to check the iodine level in our diet and adjust it to the recommended amount to evaluate our hormonal system.
Important Facts about Hypothyroidism and Health Insurance in Spain Hypothyroidism has been known since 1850 when comprehensive research was conducted on the thyroid following the removal of this gland in people with goiter.
Today, more than 300 million people live in Spain, of whom 1,600 are at risk, suffering from some type of thyroid disease. However, due to the difficulty of differentiating its symptoms from other common diseases, many people are unaware that they have it. According to this study and based on the concerning increase in the disease, we have provided all the necessary tools to keep your life healthy and protected with our specialized health insurance.
