Orthostatic hypotension is a sudden drop in blood pressure when getting up from a sitting or lying position. This can cause dizziness or even fainting.What is blood pressure?Blood pressure shows how much force the blood exerts on the walls of the arteries when the heart is working. It is measured by two indicators in millimeters of mercury (mmHg):•Systolic pressure – when the heart contracts and pushes blood out.•Diastolic pressure – when the heart rests between beats.Blood pressure is recorded as systolic/diastolic. Normal blood pressure is below 120/80 mmHg , and blood pressure below 90/60 mmHg is considered low.Why does orthostatic hypotension occur?When lying or sitting, blood easily returns to the heart. When standing up, blood pools in the legs, and there is less for the heart and brain – blood pressure temporarily drops. Possible causes:•Weak heart contractility•Dysfunction of the autonomic nervous system•Diseases such as Parkinson's or Lewy body dementia•Prolonged bed rest•Blood or fluid loss•Adrenal gland problems•Medication side effectsWhat are the symptoms?Symptoms usually worsen in the morning when blood pressure is at its lowest. Some people have no symptoms, while others find them worse in hot weather, with fever, or after a hot shower.The main symptom is dizziness or weakness when standing up, which resolves when sitting or lying down.Other possible signs include:•Fainting•Blurred vision•Fatigue, weakness•Chest, neck, or shoulder pain•Difficulty concentrating•Headaches•Rapid heartbeat•Nausea, sweating•Shortness of breathHow is it diagnosed?A doctor will measure your blood pressure while lying down, sitting, and standing. They may also order:•Blood tests (e.g., for anemia or diabetes)•ECG – to assess heart rhythm•EchoCG – to check how the heart works•Stress test•Holter monitoring•Tilt table testWhat are the possible complications?Orthostatic hypotension can lead to:•Falls, fractures, concussions•Post-meal hypotension (especially after carbohydrate-rich meals)•Lower blood pressure when lying down•Stroke or heart disease due to blood pressure fluctuations•Organ damage if blood pressure remains lowWhat to expect?The condition is usually manageable. Simple measures, such as getting out of bed more slowly, help. Serious complications are rare.Can orthostatic hypotension be cured?There is no complete cure, but symptoms can be alleviated by following a doctor's recommendations:•Taking medications•Increasing fluid intake•Eating small, frequent meals•Wearing compression stockingsHow to reduce the risk?•Avoid very hot showers and baths•Drink enough water, limit alcohol, do not overeat•Sleep with your head elevated•Get up slowly, especially in the mornings•Do light exercises – squeeze a ball, march in place•Use compression garments (stockings, belts)If you notice signs of orthostatic hypotension, do not delay visiting a specialist. Timely diagnosis and treatment will help avoid complications and improve your quality of life.

Lowering cholesterol levels requires a comprehensive approach that includes both lifestyle changes and, in some cases, medication.Lifestyle Changes1.Heart-Healthy Diet. Diet plays a key role in cholesterol control. Doctors recommend eliminating trans fats and limiting saturated fat intake. It is also important to monitor calorie intake to avoid weight gain. The emphasis is on a varied and nutritious diet—fruits, vegetables, whole grains, and lean proteins.2.Maintaining a Healthy Weight. Excess weight is one factor that increases LDL (bad cholesterol) and lowers HDL (good cholesterol). This is especially relevant for people with metabolic syndrome—a set of conditions that increase the risk of cardiovascular disease.3.Physical Activity. Regular exercise helps lower triglycerides and LDL, while simultaneously raising HDL. The appropriate level of activity should be discussed with your doctor, especially if you have not exercised before.4.Stress Reduction. Constant psycho-emotional stress can negatively affect cholesterol balance, increasing LDL and lowering HDL. Stress management methods—from meditation to walks—can be helpful.5.Quitting Smoking. By quitting smoking, you can increase your HDL levels, which helps remove LDL from the body. This is one of the most effective steps toward improving cardiovascular health.6.Quality Sleep. 7 to 9 hours of sleep each night also affects cholesterol levels. Lack of sleep can contribute to its increase.Medication TherapyWhen lifestyle changes are not enough, doctors may prescribe cholesterol-lowering medications. There are different types of such medications, each with its own mechanism of action and possible side effects. It is important to choose the right medication in consultation with your doctor. However, even when taking medication, it is important to continue to follow a healthy lifestyle—diet, physical activity, and avoiding bad habits remain important.Additional Treatments1.Lipoprotein Apheresis. Some patients with hereditary hypercholesterolemia (FH) may require an apheresis procedure. Using special equipment, LDL is removed from the blood, after which the rest of the blood is returned to the body.2.Dietary Supplements. Many supplements are available on the market that promise to lower cholesterol. However, not all of them have proven their effectiveness. Here's what the research base shows:•Plant stanols and sterols, especially when taken with food, can lower cholesterol levels.•Soy products may have a slight positive effect. However, soy products are more effective than supplements.•Whole flaxseed and flax lignans help lower cholesterol, but flaxseed oil does not.•Garlic supplements may slightly lower cholesterol, but their effect is significantly weaker than that of medications.Always consult your doctor before taking any supplements. Some of them may cause side effects or interact with medications.

Summer is a wonderful time to be outside all day, running, playing, and having an incredibly fun time, but with all that, the risk of developing heatstroke, burns, and dehydration is high. Therefore, it is important to know the simple rules for sun protection:•Try to stay indoors at midday to avoid the sun's strong and harmful rays (specifically between 10:00 AM and 4:00 PM), or hide in shady places (under a tree, an umbrella, or in a tent).•Dress children in long-sleeved, cotton, loose-fitting clothes to protect exposed areas of their body.•Buy a wide-brimmed hat to cover the head, neck, and ears. This is especially important for toddlers with short hair.•Older children can wear sunglasses that will protect their eyes from the sun's UV rays (when buying, pay attention to the percentage: 97-100% UV protection).•Do not forget to use sunscreen (at least 15 SPF), applying it 30 minutes before going outside and reapplying every 2 hours.By the way, before applying the cream completely, it is important to do a patch test on a small area of the skin to check for an allergic reaction. Also, before buying a sunscreen, pay attention to the ingredients. It is desirable that it does not contain oxybenzone. The American Academy of Pediatrics does not recommend using sunscreen for children under 6 months old, but if sun exposure is unavoidable, apply a thin layer with zinc oxide or titanium dioxide.However, even slight carelessness can lead to sunburn. The first signs of a burn often appear 6-12 hours after being in the sun. A mild burn does not require special hospital treatment; this refers to localized redness, warmth, or pain on the skin. In such a case, it is important to:•Offer plenty of fluids to avoid dehydration.•Bathe only with lukewarm water.•Give the child some pain reliever (paracetamol or ibuprofen; follow the age and weight-appropriate dosage indicated in the leaflet).•Avoid various lotions and creams intended for adults, and consult a pediatrician before use.•Avoid the sun until the burned skin has healed.•Remain under the supervision of a pediatrician.In case of a more severe burn (blistering, fever, chills, headache, weakness), contact a pediatrician immediately or go to the nearest children's hospital.

It’s one of the first things new parents might notice after birth — a yellowish tint to their baby’s skin or eyes. This condition, known as jaundice, is extremely common in newborns. In fact, it affects up to 60% of full-term babies and as many as 80% of preterm infants in the first week of life.While it’s usually harmless and temporary, understanding why jaundice happens — and when it might signal a more serious issue — is important for every parent.What Is Jaundice and Why Does It Happen?Jaundice in newborns occurs when there’s too much bilirubin in the baby’s blood — a condition called hyperbilirubinemia. Bilirubin is a yellow pigment produced during the normal breakdown of red blood cells.Before birth, the mother's liver does all the work of removing bilirubin for the baby. But after birth, that job shifts to the baby’s own liver — which may not be fully developed yet. If the liver can’t filter out bilirubin quickly enough, the substance starts to build up in the baby’s body, giving their skin and eyes a yellow hue.This yellowing typically starts on the face and can spread to the chest, abdomen, arms, and legs as bilirubin levels rise. It’s easiest to spot in natural light, and in babies with darker skin, it may be more noticeable in the whites of the eyes or under the tongue.Types of Newborn JaundiceNot all jaundice is the same. There are several types, each with different causes and timeframes:1.Physiological Jaundice. This is the most common type and occurs in nearly all newborns to some extent. It usually appears within 2 to 3 days after birth and disappears on its own within one to two weeks. It’s a natural part of the baby’s adjustment to life outside the womb as their liver matures.2.Breastfeeding Jaundice. This can develop in the first week of life when a baby isn’t getting enough breast milk. It may be due to difficulties with latching, a delay in milk coming in, or infrequent feedings. Less feeding means fewer bowel movements — and that leads to slower elimination of bilirubin from the body.3.Breast Milk Jaundice. This is different from breastfeeding jaundice. It typically appears after the first week and can last for a month or longer. In this case, certain substances in the mother's milk may interfere with how the baby’s liver processes bilirubin. Although it sounds concerning, breast milk jaundice is usually harmless and doesn’t require stopping breastfeeding.4.Jaundice from Medical Conditions. In some rare cases, jaundice can be caused by underlying health problems, such as:•Blood type incompatibility between mother and baby•Bruising during birth (which increases red blood cell breakdown)•Infections like sepsis•Liver conditions, including biliary atresia•Low oxygen levels at birth•An excess of red blood cellsThese forms of jaundice are less common but more serious and require immediate medical attention.Symptoms to Watch ForThe most obvious sign is yellowing of the skin and eyes. But parents should also monitor for other warning signs that may indicate severe jaundice or related complications:•Bright yellow or orange-tinted skin•Excessive sleepiness or trouble waking for feeds•Baby is very fussy or difficult to calm•Poor feeding, whether at the breast or with a bottle•Not enough wet or dirty diapersIf jaundice seems to be getting worse after the first few days — or lasts longer than two weeks — it’s time to call your pediatrician.How Is Jaundice Treated?In most cases, no treatment is needed. As your baby’s liver matures and they begin feeding regularly, bilirubin levels naturally decrease. Frequent feedings — around 10 to 12 times a day — help stimulate more bowel movements, which remove bilirubin through the stool.However, if bilirubin levels are too high or rising quickly, your baby’s doctor may recommend phototherapy — a safe and effective treatment that uses special blue lights to help break down bilirubin in the skin.In rare, severe cases, where phototherapy isn’t enough, a treatment called an exchange transfusion may be necessary. This involves replacing a portion of the baby’s blood with donor blood to quickly reduce bilirubin levels. Fortunately, this is rarely needed with early monitoring and intervention.While jaundice in newborns can be unsettling for new parents, it’s important to know that it’s usually a normal part of development. Most cases resolve without complications, especially when babies are well-fed and monitored closely.Still, severe jaundice can pose serious risks, including brain damage if left untreated — so staying informed and knowing when to call your healthcare provider is essential.If you’re ever unsure, don’t hesitate to reach out to your pediatrician. When caught early, jaundice is almost always treatable and temporary.
