Without a doubt, the feeling that our body alerts us when something is not going well is a common experience. Symptoms such as fever and pain are often clear indications that something is wrong with our health. However, what not everyone knows is that there are several diseases that operate in the shadows, without emitting any signs in their early stages. Late discovery of these illnesses can seriously compromise treatment and reduce the chances of a cure.
Although diseases such as diabetes, depression and hypertension are among the most well-known in this category, the list of conditions that can remain hidden for some time is extensive. That’s why the importance of keeping up to date with exams and making regular visits to the doctor should not be underestimated, even when you feel healthy.
With that in mind, today we’re going to explore some of the silent illnesses that deserve your attention and understanding. After all, information and prevention are the best allies in the search for a healthy and balanced life.
1. Type 2 diabetes
Type 2 diabetes is one of the most prevalent health conditions in Brazil, affecting around 12.5 million people, which corresponds to 7% of the population. While type 1 diabetes is typically an autoimmune disease diagnosed in childhood, the more common type 2 diabetes develops when the body cannot produce enough insulin to regulate blood sugar levels.
The insidious nature of type 2 diabetes means that its symptoms take time to manifest, often attacking the body’s blood vessels and nerves before it is identified.
2. Depression
Depression is an insidious mental disorder that often begins with feelings of discouragement and fatigue, progressing to deep sadness and, in some cases, leading to self-destructive behaviors such as alcohol abuse or binge eating. Lack of physical activity is also a common symptom associated with depression.
The stigma surrounding mental illness often leads to delayed diagnosis and prolonged suffering. Therefore, it is crucial to recognize the early signs of depression, such as changes in sleep patterns, loss of interest in activities once enjoyed, and persistent feelings of sadness. Seeking professional help and emotional support is essential to effectively cope with this condition.
3. Hepatitis C
The good news is that modern treatment has proven to be highly effective, with cure rates greater than 95%, and lasts on average just 12 weeks.
Hepatitis C is primarily transmitted through contact with contaminated blood, such as sharing needles, transfusions of untested blood, and inadequately sterilized invasive medical procedures.
4. Hypertension
Hypertension, or high blood pressure, is a condition that affects a large number of people around the world. However, many are unaware that they have this problem, as it is often asymptomatic in its early stages. When blood pressure consistently exceeds 140/90 mmHg (or 14 over 9), a person is diagnosed with hypertension.
Risk factors such as family history, smoking, obesity, excessive salt consumption and stress can contribute to the development of hypertension. Maintaining a balanced diet, exercising regularly, avoiding smoking and reducing sodium intake are essential preventative measures to control blood pressure. Routine medical exams are equally crucial to identifying and treating high blood pressure before it causes significant harm.
5. Aids/HIV
Acquired Immunodeficiency Syndrome, better known as AIDS, is a condition that develops as a result of infection with the human immunodeficiency virus (HIV). This virus acts silently and gradually destroys the immune system’s defense cells, making the body susceptible to opportunistic infections. HIV symptoms usually take time to appear and often only appear in advanced stages of the disease.
HIV prevalence is a global concern, with approximately 5,000 new HIV-positive cases being diagnosed daily around the world, according to the WHO. In 2022, almost one million people lost their lives to AIDS.
The importance of awareness, prevention and regular testing cannot be underestimated. HIV tests are widely available and can provide vital information for early treatment and preventing the spread of the virus.
6. High cholesterol
Cholesterol, a lipid substance essential for the body’s functioning, can become a threat when present in excess in the body. The accumulation of fat particles in veins and arteries due to high cholesterol can lead to narrowing of these blood pathways, putting a strain on the heart and increasing the risk of cardiovascular disease.
Several factors, such as family history, physical inactivity, obesity, smoking, diabetes and poor diet, contribute to high cholesterol levels. Maintaining a healthy lifestyle, including a balanced diet and regular physical activity, is critical to controlling this silent threat to cardiovascular health.
7. Anemia
Anemia is a condition in which the body does not produce enough red blood cells due to iron deficiency. This results in the body’s inability to transport oxygen effectively, leading to symptoms such as weakness, tiredness, shortness of breath, paleness and palpitations. Women with heavy menstrual flow are particularly at risk of developing anemia.
Early diagnosis and treatment are crucial to reversing anemia and restoring vitality. Raising awareness about the importance of iron in the diet and seeking appropriate medical care are essential steps to combat this condition.
8. Endometriosis
Endometriosis is a condition that occurs when the tissue that normally lines the uterus, known as the endometrium, begins to grow in other organs of the body, such as the ovaries, bladder and fallopian tubes. This can result in extremely painful menstrual cramps and other debilitating symptoms. It is estimated that up to 10% of women of reproductive age suffer from this condition.
Endometriosis is often underdiagnosed, and the suffering of affected women is often ignored. However, raising awareness about this disease and seeking specialized treatment are crucial to alleviate pain and improve patients’ quality of life.
In this scenario of silent diseases, education and prevention play a vital role in maintaining health and well-being. Being aware of subtle signs, adopting a healthy lifestyle and seeking regular medical care are key measures to detect, treat and, when possible, prevent these health conditions.
9. Osteoporosis
As we cross the age of 30, our body begins a gradual process of reducing the capacity for bone regeneration, a phenomenon that becomes more pronounced as we age. This natural process results in the loss of bone density, making bones more fragile and susceptible to fractures. Surprisingly, the diagnosis of osteoporosis is often only established after an injury or accident, and women are particularly vulnerable to this condition.
Numerous factors contribute to the development of osteoporosis, including low calcium intake, smoking and lack of physical activity. This disease, often silent in its early stages, deserves special attention as it significantly affects people’s quality of life and independence as they age. Awareness about prevention, early detection and appropriate treatment play a key role in the fight against osteoporosis.
10. Thyroid dysfunction
Thyroid gland dysfunction can have a profound impact on our health and well-being. Hypothyroidism, characterized by insufficient production of thyroid hormones, slows down metabolism, leading to symptoms such as weight gain, fatigue, muscle pain, digestive disorders and mood changes. In contrast, hyperthyroidism, marked by excess thyroid hormones, can trigger excessive sweating, nervousness, rapid heartbeat and unintentional weight loss.
The subtleties of these thyroid disorders can go unnoticed, making diagnosis challenging. However, knowing the symptoms and seeking medical help are crucial to ensuring adequate treatment and improving the quality of life of those affected.
Without a doubt, the feeling that our body alerts us when something is not going well is a common experience. Symptoms such as fever and pain are often clear indications that something is wrong with our health.
