What is a Holter monitor?
A Holter monitor is a small, wearable medical device used to continuously record the electrical activity of your heart over an extended period, usually 24 to 48 hours, and sometimes longer. It’s a type of ambulatory electrocardiogram (ECG/EKG), meaning it monitors your heart while you go about your normal daily routine outside of a clinic or hospital.
Unlike a standard ECG, which captures your heart’s activity for just a few minutes while you’re resting, a Holter monitor provides a much broader picture. By recording every heartbeat over one or more days, it helps healthcare providers detect heart rhythm problems that may appear only occasionally or during specific activities such as exercise, stress or sleep.

How a Holter monitor works

Your heart beats because of natural electrical impulses that control the timing and rhythm of contractions. A Holter monitor records these impulses through electrodes placed on your chest.
The system usually includes:

Electrodes

– small adhesive patches attached to the skin that detect electrical signals

Wires

– connect the electrodes to the recording device (some newer models are wireless patch-style units)

Recording device

– a lightweight, battery-powered monitor worn on a belt, strap or in a pocket
The device stores all the data while you wear it. Your healthcare provider reviews the recordings only after you return the monitor—there’s no real-time monitoring.

Why a Holter monitor may be needed

Your healthcare provider might recommend a Holter monitor if symptoms suggest a heart rhythm issue that isn’t visible on a resting ECG. It’s especially useful when symptoms are intermittent.

Common reasons include:

• Dizziness, fainting or unexplained fatigue
• Heart palpitations or irregular heartbeats
• Chest discomfort or shortness of breath
• Evaluating how well heart medications or a pacemaker are working
• Assessing heart rhythm changes after a heart attack or in certain heart conditions
Because the monitor records continuously, it increases the chance of capturing abnormal rhythms such as very fast, very slow or irregular heartbeats.

What to expect while wearing a Holter monitor

Getting set up is simple and usually done on an outpatient basis. After the electrodes or patch are placed on your chest, you can return to most of your normal activities, including work and light exercise, unless your provider advises otherwise.

You’ll likely be asked to:

• Keep a diary of activities and symptoms (noting time, activity and how you felt)
• Avoid getting the device wet (no showering, bathing or swimming)
• Stay away from strong magnetic or high-voltage environments that could interfere with the recording
Recording what you’re doing when symptoms occur helps your provider match those moments with changes seen in your heart rhythm.

Risks and limitations

A Holter monitor is safe and painless. Risks are minimal, but some people may notice:
• Mild skin irritation or itching where electrodes are attached
• Discomfort when electrodes are removed
• Loosening of electrodes due to sweating
Electrical appliances, magnets or cell phones placed too close to the device may interfere with signal quality, so following instructions is important.

After the monitoring period

Once the monitoring time is complete, you return the device to your healthcare provider. The data from the monitor, along with your activity diary, is analyzed to look for abnormal heart rhythms, pauses or unusual rate changes.
Results may show normal heart activity or detect rhythm disorders such as atrial fibrillation, bradycardia (slow heart rate), tachycardia (fast heart rate) or extra beats. Your provider will explain the findings and discuss next steps, which may include additional tests, medication adjustments or other treatments if needed.
A Holter monitor is a valuable, noninvasive tool that helps healthcare providers better understand how your heart behaves throughout your everyday life—not just in a brief moment in the exam room.
If you have heart-related symptoms, you can visit Dalimed Medical Center for a specialist consultation and, if needed, undergo Holter monitoring using modern equipment in a comfortable clinical setting.
Migraine or ordinary headache? How to tell the difference
29 May 2026
Almost everyone experiences headaches from time to time. Stress, lack of sleep, dehydration, or long hours in front of a screen can all lead to head pain. But sometimes what seems like an ordinary headache may actually be a migraine. Although many people use the words “migraine” and “headache” interchangeably, they are not the same condition. A migraine is a more complex neurological disorder that often comes with additional symptoms beyond head pain. Understanding the difference can help you choose the right treatment and know when it is time to seek medical help. What does an ordinary headache feel like? The most common type is a tension headache. It usually causes: • A dull, aching pain • Pressure or tightness around the forehead or sides of the head • Mild to moderate discomfort • Pain on both sides of the head Tension headaches are often linked to stress, anxiety, muscle strain, fatigue, or poor sleep. While uncomfortable, they are usually manageable and often improve with rest, hydration, or over-the-counter pain relievers. What makes a migraine different? A migraine is typically more intense and disruptive than a regular headache. The pain is often throbbing or pulsating and may affect one side of the head, although both sides can sometimes be involved. Migraine attacks can last anywhere from several hours to even a few days if untreated. In addition to head pain, migraines may cause: • Nausea or vomiting • Sensitivity to light, sound, or smells • Blurred vision • Neck pain or fatigue • Difficulty concentrating For many people, normal daily activities become difficult during a migraine attack. Some need to rest in a dark, quiet room until the symptoms improve. What is migraine aura? Some people experience warning signs before the migraine begins. This is called aura. Aura may include: • Flashing lights or zig-zag lines • Tingling or numbness in the face or hands • Temporary vision changes • Difficulty speaking clearly These symptoms usually develop gradually and may last up to an hour before the headache starts. Other types of headaches Certain headaches can sometimes be mistaken for migraines. Sinus headache. Sinus headaches usually cause pressure around the forehead, cheeks, or nose and are often accompanied by nasal congestion or thick mucus related to infection.Cluster headache. Cluster headaches are rare but extremely painful. They usually cause sudden stabbing pain around one eye, often with tearing or a stuffy nose. Unlike migraines, cluster headaches appear suddenly and typically last a shorter time.Common migraine triggers Migraine attacks can be triggered by different factors, including: • Stress • Hormonal changes • Lack of sleep • Skipping meals • Dehydration • Weather changes • Certain foods or alcohol • Excess caffeine Triggers vary from person to person, and keeping a headache diary may help identify patterns. When should you see a doctor? Occasional headaches are common, but medical evaluation is important if: • Headaches happen frequently • Pain interferes with daily activities • Over-the-counter medications stop helping • You experience nausea, vision changes, or neurological symptoms • A sudden severe headache appears unexpectedly A doctor may recommend further evaluation to rule out other neurological or medical conditions. Migraines can significantly affect quality of life, but with proper diagnosis and treatment, many people are able to reduce both the frequency and severity of attacks.
Why Hair Loss Happens: Hormones, Stress, or Vitamin Deficiency?
25 May 2026
Losing some hair every day is normal. Most people shed around 50–100 hairs daily as part of the natural hair growth cycle. Problems begin when hair falls out faster than it can grow back, leading to noticeable thinning or bald patches. Hair loss, also called alopecia, can affect both men and women and may develop gradually or suddenly. Common Causes of Hair Loss Genetics and Hormones The most common cause is hereditary hair loss, known as androgenic alopecia. Men often develop a receding hairline or thinning at the crown, while women usually notice overall thinning and a wider hair part. Hormonal changes from pregnancy, menopause, thyroid disorders, or conditions like PCOS can also trigger hair shedding. Stress and Illness Physical or emotional stress may cause temporary hair loss. Surgery, illness, rapid weight loss, or difficult emotional experiences can push more hairs into the shedding phase. This often appears a few months after the stressful event. Vitamin Deficiencies Low levels of iron, protein, vitamin D, and certain B vitamins may weaken hair growth. Vitamin D is especially important because it helps support hair follicles. Deficiency may also cause fatigue, muscle weakness, and low mood. Other Possible Reasons Hair loss can also result from: • Autoimmune conditions such as alopecia areata • Certain medications, including chemotherapy • Scalp infections • Tight hairstyles that pull on the hair • Frequent bleaching or heat styling When Should You See a Doctor? You should seek medical advice if you notice: • Sudden or excessive hair shedding • Bald patches • Itching or pain on the scalp • Hair loss together with fatigue or hormonal symptoms Doctors may recommend blood tests to check iron levels, thyroid function, or vitamin deficiencies. Can Hair Loss Be Treated? Treatment depends on the cause. Correcting nutritional deficiencies or hormonal imbalances may help reduce shedding. Other options include topical treatments, PRP therapy, and hair transplantation in selected cases. To support healthy hair growth: • Eat a balanced diet • Avoid tight hairstyles and excessive heat • Manage stress • Treat medical conditions early Although hair loss can be frustrating, many cases improve once the underlying cause is identified and treated.
Kidney stones: Causes, symptoms, and treatment
20 May 2026
Kidney stones are hard deposits that form inside the kidneys when minerals and salts in the urine begin to stick together and create crystals. These stones can be tiny like a grain of sand or grow much larger over time. Some pass out of the body without causing symptoms, while others may block the urinary tract and lead to severe pain or complications. Kidney stones are a common urinary system problem and can affect people of all ages, although they are seen more often in adults, especially men. Once a person develops a kidney stone, the risk of getting another one in the future becomes higher. Why do kidney stones form? Urine naturally contains substances such as calcium, oxalate, uric acid, and other minerals. Normally, these substances dissolve in liquid and leave the body safely. However, when urine becomes too concentrated or certain chemicals rise to high levels, crystals may start forming and gradually turn into stones. Several factors can increase the risk of kidney stones, including: • Not drinking enough water • Diets high in salt, sugar, or animal protein • Family history of kidney stones • Obesity and metabolic disorders • Recurrent urinary tract infections • Certain medications or high-dose supplements • Digestive diseases or previous intestinal surgery Some medical conditions such as gout, diabetes, hyperparathyroidism, or cystinuria can also make stone formation more likely. Main types of kidney stones There are several different kinds of kidney stones, and each develops for different reasons: • Calcium stones – the most common type, usually formed from calcium combined with oxalate or phosphate • Uric acid stones – often linked to diets rich in meat and seafood • Struvite stones – associated with urinary tract infections and may grow quickly • Cystine stones – a rare inherited form caused by a genetic condition Understanding the type of stone is important because it helps guide treatment and prevention. Symptoms of kidney stones Small stones may pass unnoticed, but larger stones can become trapped in the urinary tract and cause intense symptoms. Pain usually begins suddenly and may come in waves. Common symptoms include: • Sharp pain in the lower back, side, or abdomen • Pain spreading toward the groin • Blood in the urine • Burning or pain during urination • Frequent urge to urinate • Nausea and vomiting • Cloudy or foul-smelling urine • Fever or chills if infection develops In some cases, kidney stones may block urine flow and lead to swelling of the kidney, infection, or even kidney damage if left untreated. How are kidney stones diagnosed? Doctors use several methods to confirm kidney stones and determine their size and location. Diagnosis may include: • Urine analysis to check for blood, crystals, or infection • Blood tests to evaluate kidney function and mineral levels • Ultrasound examination • CT scan or X-ray imaging If a stone passes naturally, doctors may ask the patient to collect it for laboratory analysis. Treatment Treatment depends on the size of the stone, its location, and the severity of symptoms. Small stones often pass on their own within several days or weeks. During this time, patients are usually advised to drink plenty of fluids and may receive medication to reduce pain or help relax the urinary tract. Larger stones or stones causing blockage may require medical procedures such as: • Shock wave lithotripsy (ESWL) – sound waves break the stone into smaller fragments • Ureteroscopy – a thin instrument is passed through the urinary tract to remove or break the stone • Percutaneous nephrolithotomy – used for very large stones through a small incision in the back Traditional surgery is now less common but may still be needed in rare complicated cases. Can kidney stones be prevented? Although kidney stones can recur, many cases are preventable with lifestyle changes. Prevention usually focuses on reducing the concentration of stone-forming substances in urine. Helpful prevention tips include: • Drink enough water throughout the day • Reduce salt and sugary foods • Avoid excessive animal protein • Maintain a healthy body weight • Treat urinary infections promptly • Follow medical advice regarding supplements and medications Some people may also need a personalized diet plan depending on the type of stone they develop. Early diagnosis and proper treatment help prevent complications and protect kidney health.
Why we need folic acid
16 May 2026
Folic acid, also known as vitamin B9, is an important vitamin that helps the body grow, repair, and function properly. It is involved in the production of new cells, making red blood cells, and supporting healthy brain and nervous system function. Although folic acid is most commonly associated with pregnancy, it is actually essential for people of all ages. Folic acid is the synthetic form of folate, a vitamin naturally found in foods. Since the body cannot store large amounts of it, regular intake through food or supplements is important. This vitamin has several important functions in the body, including: • Supporting cell growth and DNA production • Helping form healthy red blood cells • Supporting brain and heart health One of the most well-known benefits of folic acid is its role during pregnancy. In the early weeks of pregnancy, it helps the baby’s brain and spinal cord develop properly. Adequate folic acid intake significantly lowers the risk of serious birth defects such as spina bifida. Because these changes happen very early — often before a woman even knows she is pregnant — doctors recommend that women of reproductive age get enough folic acid daily. A lack of folic acid may lead to folate-deficiency anemia, a condition in which the body cannot produce enough healthy red blood cells. Common symptoms may include: • Fatigue and weakness • Pale skin • Dizziness or shortness of breath Folic acid may also contribute to overall wellness by helping regulate homocysteine, a substance linked to heart disease when present at high levels. Some studies also suggest that healthy folate levels may support memory, mood, and cognitive function. Good dietary sources of folate include: • Leafy green vegetables • Beans and lentils • Citrus fruits • Eggs and nuts • Fortified cereals and grain products Most adults need around 400 micrograms of folic acid daily, while pregnant women usually require higher amounts. Supplements may be recommended in certain situations, especially during pregnancy or in people with absorption problems. Overall, folic acid is a small but essential nutrient that supports many important processes in the body. From healthy blood cells to proper fetal development, getting enough folic acid is an important part of maintaining good health. Check your folic acid levels now at Dalimed Medical Center.
