Understanding and Preventing Deep Vein Thrombosis

Deep Vein Thrombosis (DVT) is a medical condition where a blood clot forms in a deep vein, typically in the legs. This can lead to pain, swelling, and in severe cases, can cause clots to break free and travel to vital organs, such as the lungs, leading to life-threatening complications. Recognizing the factors that increase the risk of DVT and adopting preventive measures is crucial for maintaining vascular health.

Risk Factors for DVT  

Here are the factors that can elevate your risk of developing DVT: 

 

Previous Blood Clot: Individuals who have experienced DVT are at a heightened risk of recurrence. 

 

Family History: A genetic predisposition to DVT is significant. The risk is further amplified if both parents have a history of the condition. 

 

Age: The likelihood of DVT increases with age, particularly for those over 40. 

 

Prolonged Immobility: Extended periods of immobility, such as bed rest due to hospitalization or long-duration flights, can significantly increase the risk of DVT. When muscles are not active, blood flow in the deep veins of the legs slows down, making it easier for clots to form. This is why it's crucial to take breaks, move around, and stretch regularly during prolonged sitting or when confined to a bed or chair for extended periods. 

 

Gender and Age: Men aged between 45 and 60 are slightly more susceptible to DVT. However, women's risk may increase during pregnancy due to hormonal changes. 

 

Genetic Factors: Genetic predispositions play a significant role in the risk of developing DVT. Conditions such as Factor V Leiden mutation increase the blood's tendency to clot. While a single genetic factor may not cause DVT on its own, in combination with other risks, it can significantly increase the likelihood of clot formation. Knowing family history and discussing genetic testing with a healthcare provider can help assess and manage this risk. 

 

Pregnancy and Hormone Therapy: Elevated estrogen levels during pregnancy or from hormone-based medications can increase clotting risk. Apart from pregnancy, other conditions and medications that alter hormone levels can also elevate DVT risk. This includes hormone replacement therapy and certain types of birth control. The increased estrogen can make the blood more prone to clotting. It's essential for individuals undergoing these treatments to consult with their healthcare providers about their specific risk and possible preventive measures. 

 

Clotting Disorders: Inherent blood clotting disorders can lead to abnormally thick blood.

Obesity: Obesity is a significant risk factor for DVT. Excess weight, especially around the abdomen, can exert additional pressure on the veins in the pelvis and legs, impeding blood flow back to the heart. This can lead to blood pooling and clot formation. Furthermore, obesity alters the chemical composition of the blood, increasing its propensity to clot. Managing weight through diet, exercise, and lifestyle changes can help reduce the risk of DVT and improve overall health. 

 

Health Conditions: Diseases like heart disease, lung disease, inflammatory bowel disease, and cancer can elevate DVT risk. 

 

Injury or Surgery: Physical trauma, such as a bone fracture or muscle injury, can damage blood vessels and lead to clot formation. Similarly, surgeries, particularly those involving the abdomen, pelvis, hip, or legs, can increase the risk of DVT due to immobility during recovery and potential damage to blood vessels. Taking preventive measures, such as using compression stockings or medication for blood thinning as recommended by healthcare providers, can help reduce this risk. 

 

Chronic diseases: Certain chronic conditions, such as heart disease, cancer, and inflammatory bowel disease, can increase the risk of DVT. These diseases can alter blood flow, contribute to inflammation, and affect the blood's ability to clot. For instance, cancer and its treatments can increase clotting factors in the blood, while heart disease can lead to reduced mobility and blood flow. Managing these conditions with the guidance of healthcare professionals is crucial for minimizing DVT risk. 

 

Inflammatory Diseases: Conditions like inflammatory bowel disease (IBD) not only disrupt the digestive tract but also contribute to a systemic inflammatory response. This state of heightened inflammation can increase the risk of blood clot formation. Managing inflammation through appropriate treatments and lifestyle changes is crucial.

Strategies to Lower DVT Risk  

While some risk factors for DVT cannot be modified, several strategies can help mitigate the risk:

 

 Avoid Prolonged Immobility: Stand, stretch, or walk at least every 2 hours. Perform simple leg exercises even while seated. If you work at a desk or engage in activities that require sitting for extended periods, integrate short breaks into your routine. Use a timer as a reminder to stand up or stretch every hour. Even minimal movements, such as ankle circles or foot pumps, can stimulate blood flow in your legs.

Post-Surgery Mobility: After surgery, particularly operations involving the abdomen, pelvis, hip, or legs, it's crucial to start moving as soon as medically advised. Gentle exercises, like ankle pumps, knee bends, and leg lifts, can be performed even in bed. These movements help in maintaining circulation and preventing blood clots. 

 

Medical Consultation: Discuss with a healthcare provider about the potential need for blood thinners or compression stockings if at high risk. 

 

Travel Precautions: During long flights or car rides, make it a point to stand or walk around every couple of hours. Choose seats that offer more legroom when possible, and perform seated exercises like foot lifts or knee bends. Wearing loose, comfortable clothing and staying hydrated are essential, while avoiding alcohol and caffeine, which can lead to dehydration. 

 

Stay Active: Regular physical activity is beneficial for overall health and plays a key role in preventing DVT. Activities like walking, swimming, or cycling improve circulation and vein health. Aim for at least 30 minutes of moderate exercise most days of the week. Even those with limited mobility can find suitable exercises to keep blood flowing efficiently. 

 

Health Management: Addressing obesity, quitting smoking, and managing chronic diseases are crucial steps in reducing DVT risk. 

 

Lifestyle Adjustments: For individuals who are overweight, losing weight can significantly reduce the pressure on veins in the legs and improve blood flow. Quitting smoking is also crucial, as smoking affects blood circulation and increases the risk of clotting. Managing chronic conditions such as diabetes, high blood pressure, and heart disease through medication, diet, and exercise is vital in reducing the risk of DVT.

 

Proactive Health Checks: For those with a high risk of DVT, regular check-ups and screenings can be lifesaving. This includes monitoring for any signs of clotting disorders, reviewing medication impacts, and assessing the need for preventive measures like compression garments or anticoagulants.

Lymphatic disorder may cause stillbirth, chronic disease in affected children

In a breakthrough discovery, South Australian researchers have identified a genetic mutation responsible for a lymphatic disorder that may be responsible for causing stillbirth or severe, chronic disease in affected children.

The findings were published in the journal 'Science Translational Medicine'.

An anomaly in the development of lymphatic vessels in unborn children, leading to fluid accumulating in the heart, lungs, and other organs, was uncovered by the scientists from the Centre for Cancer Biology (CCB) based at the University of South Australia (UniSA) and SA Pathology.

CCB Director Professor Natasha Harvey said a genetic study of six families affected by stillbirth or lymphoedema revealed the link between a mutated protein-coding gene called MDFIC and fluid accumulation in vital organs and tissues.

This demonstrated that MFDIC is important for controlling the growth and development of the lymphatic vessels in the foetus for the first time.

"The lymphatic system is a network of vessels (pipes) and nodes (filters and control centres) important for maintaining fluid balance in our tissues and transporting infection-fighting white blood cells throughout our bodies," Prof Harvey said.

"We determined that MDFIC controls cell migration, an important early event during the formation of the lymphatic vessel valves. The genetic variants we have found in our study reveal a crucial, previously unrecognized role for MDFIC in the lymphatic vasculature."

"If the lymphatic valves don't form properly, lymph fluid accumulates in critical organs such as the heart and lungs, causing major respiratory problems that may eventuate in stillbirth or chronic disease."

An SA Pathology research team headed by Professor Hamish Scott initially found the genetic link in an Australian family. Their international colleagues in Belgium, Germany, and the US reported variants in the same gene, MDFIC, in several patients with the same lymphatic disorder.

Prof Harvey said, the disorder, known as the central conducting lymphatic anomaly (CCLA), is one of a group of severe lymphatic disorders and may result in stillbirth, or severe chronic disease in affected children.

Few effective treatments are available but with continued identification of the genetic causes of CCLAs, Prof Harvey says the next step is to develop new therapeutic drugs to combat the disease.

"There are existing drugs that may be used to treat these disorders, but we need to make sure that the signalling pathway that's treated by those drugs is the same pathway that is affected in our patients.

"This project is about the power of collaboration at a local level, national level, and international level, so that's been really important. Science is done in teams and we have great research teams here in Adelaide at the Centre for Cancer Biology. Our Ph.D. students and postdoctoral fellows have been integral to this work. They have really driven it and we're delighted to be working with such a group of talented people."

Zinc – How to Tell If You Have A Deficiency

Proper growth of the body, intracellular metabolism and the creation of DNA are just some of the processes for which zinc is essential, so it's no wonder that a zinc deficiency can cause impaired functioning of the body's entire system. This mineral deficiency is more common in people over the age of 60 and in people whose diets are vegan or vegetarian. What these two groups have in common is the fact that they consume a diet rich in legumes and grains that do not contain enough zinc. In fact, the foods they consume have ingredients that prevent zinc from being absorbed by the body.

So, how do you know if you have a zinc deficiency? Regular medical tests don’t always show if there is a deficiency in this mineral, but there are some signs that may indicate a lack of it in the body. The good news is that you can increase the level of zinc in your body quite easily - you just need to know which foods are rich in this mineral.

6 signs of zinc deficiency 

 

1. Frequent infections and diseases 

Zinc plays a central role in the proper functioning of the immune system and prevention of infections. When you don't consume enough zinc, your immune system may function poorly and won’t be able to ward off viral and bacterial infections. Also, if you feel that you’ve been in a lot of pain recently, you may not be consuming enough zinc. 

2. Abnormal hair loss  

It’s natural to lose a few hairs while brushing it, but if you notice that the amount of hair left behind on your brush has increased significantly, it could be due to a lack of zinc. It's worth noting that only a significant zinc deficiency can cause huge hair loss and breakage, but you should keep an eye on the problem nevertheless.

3. Chronic diseases  

Neurological disorders, autoimmune diseases, and diabetes are just some of the diseases researchers have found to be related to a zinc deficiency. This deficiency causes increased oxidation processes in the body, leading to inflammation, cell death, and an increased risk of chronic disease. A balanced diet that includes foods with high concentrations of zinc can delay the formation of chronic diseases. 

 

4. Decline in hearing 

Researchers have found that people with hearing loss might also have a zinc deficiency. The researchers believe that this is due to inflammation and decreased pressure in the inner ear as a result of zinc deficiency. If you feel that your hearing is not what it used to be, you body may be lacking zinc. zinc

5. Decrease in growth rate 

Children with a zinc deficiency may experience a decrease in growth rate. Due to the role of zinc in the normal development of cells and body growth, a lack of it causes problems with physical growth, meaning that children who do not consume enough of this essential mineral are shorter than average for their age. If you notice a low growth rate in your children, incorporate zinc-rich foods in their diet. If there is no change in their growth rate, it's recommended that you take them to get their zinc levels tested. 

 

6. The taste of the food has changed 

Other senses besides the sense of hearing that may be damaged due to zinc deficiency are sense of taste and sense of smell. If you feel that foods have a different taste suddenly, this may be indicative of a zinc deficiency. This is especially true for people over the age of 60, as zinc deficiency is more common in this age group, and other factors, such as increased drug use, may exacerbate the ability to taste and smell.

 

So how can you consume more zinc?  

The good news is that zinc deficiency can be easily corrected by adding foods rich in this mineral to your daily diet. It's important to eat these foods every day since the body doesn’t store zinc and only daily consumption will result in constant adequate zinc levels in the body. Women should consume about 8 mg of zinc a day, men about 11 mg daily, and people with different diseases or significant zinc deficiency will need larger amounts depending on their health. 

 

People who are vegan or vegetarian should sometimes consume twice as much as the recommended daily amount, as their bodies absorb zinc less efficiently and some vegetables can even interfere with zinc absorption in the body. If you feel that you’ve been sicker lately or have some of the symptoms mentioned above, you should prepare zinc-rich dishes so that you can enjoy healthier hair, get sick less, and getting back the taste for life, literally. However, be careful not to consume too much zinc, as in excess it can cause headaches, nausea, and anemia. 

 

8 Recommended zinc-rich foods  

* The amounts of zinc given are per serving size of 100 grams.

1. Beef  

Beef is full of flavor and nutritional benefits, which include, apart from a high zinc content (7 mg per serving), large amounts of protein and vitamin B12. Despite these benefits, it's recommended not to overeat meat because it also contains large amounts of fat. It's best to eat beef once or twice a week and to incorporate other zinc-rich foods into your diet the rest of the week. 

 

2. Toasted wheat germ  

A dose of toasted wheat germ will provide you with 16.7 mg of zinc and enrich your daily diet. You can eat wheat germ in its natural form, without toasting, and enjoy its nutritional benefits, which include aiding in digestion and delaying the narrowing of central blood vessels in the body. 

 

3. Pumpkin seeds 

Pumpkin seeds are known as a great healthy snack for after a meal, but you can also add them to salads or shakes to increase your daily zinc intake. A dose of pumpkin seeds contains about 10.3 milligrams of zinc and serves as a healthy, tasty and balanced snack.

4. Red beans 

Red beans are low in calories but rich in zinc, about 2.79 mg per serving, and can be eaten when cooked and seasoned as a standalone meal or as a side to a variety of foods. 

 

5. Mushrooms  

Mushrooms are low in calories, contain 7.66 mg of zinc, and many vitamins and minerals. In addition, its high antioxidant content is similar to that of carrots or tomatoes, and selenium chlorine, which is a mineral not usually found in plant sources, can also be obtained from their eating them. 

 

6. Egg yolks  

For those who’ve given up this part of the egg, you should put it back on the menu. Egg whites are not as rich in zinc as yolks, so you should eat the egg in its entirety if you want to increase your intake of this essential mineral. A serving of egg contains 4.93 g of zinc in addition to vitamins A, E, D and K.

7. Cocoa and chocolate  

Cocoa and chocolate products will delight anyone who has a sweet tooth, and if you eat them moderately they will do wonders for your body. A serving of chocolate (dark chocolate is preferred) contains 9.6 mg of zinc so you can refill your zinc levels with a smile.

 

8. Turkey breast 

Roasted turkey breast is tasty, rich in protein and zinc and low in calories when compared to other types of meat, such as beef. A dose of turkey breast will supply your body with about 3.09 milligrams of zinc.
