Doctor's Notes on Phlebitis
Phlebitis is the medical term for inflammation of a vein. Veins are the blood vessels that collect blood and return it to the heart for delivery to the lungs. Thrombophlebitis is phlebitis that occurs together with a blood clot (thrombus) inside of a vein. Phlebitis has many causes. Some of the most common causes include trauma or injury, prolonged immobility, insertion of intravenous (IV) catheters, burns, and certain surgical procedures.
Symptoms of phlebitis include:
- swelling, and
- tenderness at the affected area.
If the condition occurs in the leg, it may be difficult to walk. Feeling a cord-like structure along the course of a vein is a possible sign of thrombophlebitis. Other associated symptoms can include fever and drainage of pus. Mild cases of phlebitis may be asymptomatic, meaning that no symptoms are present.
What Is the Treatment for Phlebitis?
Superficial vein phlebitis of the upper and lower extremities can be treated by:
- Applying warm compresses
- Elevating the affected area
- Encouraging ambulation (walking)
- Oral or topical anti-inflammatory medications
Deep vein phlebitis may require treatment with blood-thinning (anticoagulation) medications. Certain people with extensive deep vein thrombosis (DVT) may require catheter-directed thrombolysis or placement of inferior vena cava filters to help prevent pulmonary embolus.

Blood ClotsBlood is supposed to clot to help repair a blood vessel that is injured. Clots or thrombi become a problem when they form inappropriately. There are a variety of illnesses and risk factors that can lead to blood clot formation such as atrial fibrillation, heart attack, strokes, transient ischemic attacks (TIAs), pulmonary embolism, deep vein thrombosis (DVT), and more. Diagnosis and treatment of blood clots depends on the cause and severity of the clot.
Childhood ObesityObesity means an excess amount of body fat. No general agreement exists on the definition of obesity in children as it does adults. Some define pediatric obesity as body weight at least 20% higher than the healthy weight range for a child or adolescent of that height, or as a body fat percentage above 25% in boys or above 32% in girls.
Deep Vein Thrombosis (DVT)DVT or deep vein thrombosis is a blood clot in the leg. Symptoms include redness, swelling, pain, and warmth around the area of the clot. Learn about causes, diagnosis, and treatment.
ObesityMore than two-thirds of Americans are overweight, including at least one in five children. Nearly one-third are obese. Obesity is on the rise in our society because food is abundant and physical activity is optional. The safest way to lose weight is to eat less and exercise more. Treatment may also include medications, surgery, and behavior modification.
Pregnancy Week by WeekPregnancy occurs when an egg is fertilized by a sperm, grows inside a woman's uterus (womb), and develops into a baby. In humans, this process takes about 280 days.
Pulmonary EmbolismA pulmonary embolism (PE) is a blood clot in the lung. The clot typically comes from other areas of the body and travels to the lung, where it becomes lodged. Pulmonary embolism can cause serious problems, from shortness of breath to instantaneous death, depending on the nature of the clot.
Varicose VeinsVaricose veins are thought to be inherited in some people. Other caues of varicose veins include pregnancy, prolonged standing, obesity, straining (constipation, chronic choughing, enlarged prostate, etc.), prior surgery to the leg, and age. Treatments for varicose veins include several modalities and surgery.
What Are the Health Risks of Smoking vs. Obesity?Both smoking and obesity are leading contributors to illness and death in the U.S. Smokers have a greater risk of cancer heart attack, respiratory illness (emphysema, COPD, pneumonia), high blood pressure, stroke, heart disease, peripheral vascular disease, and aortic aneurysms. Obesity can increase a person’s risk of developing high blood pressure, diabetes, heart attack, stroke, sleep apnea, osteoarthritis, and depression.
What Are the Warning Signs of Deep Vein Thrombosis (DVT)?I sit at a desk for my job, and I know a lot of sitting is a risk factor for blood clots in your leg. What are some of the warning signs of a deep vein thrombosis?
What Does It Feel Like When You Have a Blood Clot in Your Leg (DVT)?I travel a lot by airplane and I sit at a desk for my job. I have some cardiovascular problems, so I worry about blood clots forming in my legs. I want to be vigilant about potential symptoms of deep vein thrombosis. What does DVT feel like?
