1.Deficiency diseases:https://apnacare.me/?p=518
Deficiency diseases occur when the body doesn’t get enough of a specific nutrient or vitamin, leading to various health issues. Here are some common deficiency diseases:
- Scurvy: A lack of vitamin C (ascorbic acid). It can include symptoms like gum bleeding, weakly body and anemia with bruises.
Rickets: Vitamin D, calcium, or phosphate deficiency causes softening and weakening of bones that give bone deformity.
Beri-Beri: This disease results from the absence of vitamin B1 or thiamine, leading to its symptoms of nerve damage and weakened heart.
Pellagra: Caused due to the lack of vitamin B3 or niacin. Its symptoms include diarrhea, dermatitis, dementia, and if not treated, is lethal.
Anemia: Generally caused due to iron, vitamin B12, or folic acid deficiency. Its symptoms include weakness, fatigue, paleness of skin, and breathing difficulties.
Goiter: The cause of a goiter is iodine deficiency. It increases the size of the thyroid, causing swelling of the neck area.
Osteoporosis: It is related to a calcium and vitamin D deficiency. The bones become weak and brittle, thus increasing the chances of fractures.
Prevention and Management:
To prevent deficiency diseases, it’s important to maintain a balanced diet that includes a variety of nutrients:
- Fruits and Vegetables: Rich in vitamins and minerals.
- Whole Grains: Provide essential B vitamins and fiber.
- Protein Sources: Such as lean meats, fish, eggs, legumes, and nuts.
- Dairy Products: Good sources of calcium and vitamin D.
- Supplements: Sometimes necessary if dietary intake is insufficient, especially for vitamins and minerals like vitamin D, B12, and iron.
Regular check-ups and blood tests can help detect any deficiencies early and allow for prompt intervention.
2.Scurvy:
Scurvy is a disease, caused by severe deficiency in ascorbic acid, vitamin C, needed in the body to synthesize collagen. It’s a protein essential for holding tissue together-the structure of the skin, the structure of the vessels, and all the other components of bone tissue. So it’s impossible for the tissues and skin to mend without a fair amount of ascorbic acid.
Symptoms of Scurvy
The symptoms of scurvy can develop after a few months of severe vitamin C deficiency and may include:
Fatigue and generalized weakness
Swollen, bleeding gums and looseness of teeth
Joint pain and swelling
Bruising easily of the skin and small red or purple spots (petechiae)
Slow wound healing and reopening of previously healed wounds
Anemia, which causes dizziness and shortness of breath
Mood changes, including irritability and depression
Dryness, scaly nature of the skin and loss of hair
Causes of Scurvy
Scurvy is predominantly caused by diet deficiency of vitamin C. Conditions that can predispose one to scurvy include:
Low diet consumption of fruits and vegetables
Nutritional deficiency
Addiction to alcohol and drugs
Having eating disorders
Undergoing treatment with chemotherapy, among others in which the mechanism of action adversely affects nutrient intake
Prevention and Treatment Prevention and treatment are relatively easy through adequate intake of vitamin C as follows:
Eat foods rich in vitamin C, including fruits and vegetables such as oranges, strawberries, kiwi, bell peppers, broccoli, and tomatoes.
Take vitamin C supplements if necessary. This must be under a healthcare professional’s guidance.
Well-balanced diet. Eat a diet with a range of nutrients so that there is less chance of any deficiency.
Recovery
The symptoms of scurvy usually begin to improve within a few days to weeks after vitamin C reentry into the diet, and complete recovery can take about two months.
3.Rickets:
Rickets is a condition of bone development in children whereby the bones soften and weaken. This condition has the potential to cause deformity in the bone. It occurs mainly due to a deficiency of vitamin D, calcium, and phosphate. The nutrients are needed for healthy mineralization and formation of bones.
Causes of Rickets
The main causes of rickets include:
Vitamin D Deficiency: Vitamin D is essential for calcium absorption in the gut. It can occur due to a diet lacking adequate amounts, minimal sun exposure, or medical conditions that impair vitamin D metabolism.
Calcium Deficiency: Calcium is necessary for strong bones. Rickets can result from a diet lacking adequate amounts of calcium.
Phosphate Deficiency: Phosphate, along with calcium, makes solid bones. Genetics and certain defects in the kidney can cause such deficiency.
Symptoms
The symptoms may vary in each case but also include:
Delays in growth: The individuals affected by the disease are subjected to stunted growth and also short stature in comparison.
Pain and Tenderness to Bones: Notably, back, pelvis, and limbs.
Weak muscles: The impairment in the muscles caused due to weak muscles results in improper movement.
Skeletal Deformities: Such as bowed legs, thickened wrists and ankles, and a protruding breastbone (pectus carinatum).
Dental Problems: Including delayed tooth formation, defects in tooth structure, and increased risk of cavities.
Fractures: Bones may break more easily due to weakened structure.
Prevention and Treatment
Preventing and treating rickets involves ensuring an adequate intake of vitamin D, calcium, and phosphate:
Sun Exposure: Sunlight exposure will increase the body’s vitamin D production. However, the sun exposure needs to be balanced with the protection of the skin from excessive exposure.
Diet: Consuming a diet that is high in vitamin D and calcium. The following are examples of foods that provide these nutrients: fortified dairy products, fatty fish (such as salmon and mackerel), egg yolks, fortified cereals, and leafy green vegetables.
Supplements: Vitamin D supplements may be necessary for individuals who do not get enough from sunlight and diet, especially in regions with limited sunlight exposure.
Medical Treatment: In some cases, doctors may prescribe medications to treat underlying conditions that contribute to rickets, such as phosphate supplements for genetic disorders affecting phosphate metabolism.
Recovery
Most children with rickets can recover completely and grow and develop normally with proper treatment. Early diagnosis and intervention are important to prevent permanent bone deformities and other complications.
4.Beri-Beri:
Beri-Beri is a condition caused by a deficiency in vitamin B1, also known as thiamine. Thiamine is essential for the proper functioning of the nervous system, muscles, and heart. There are two main types of Beri- Beri:
Wet Beri-Beri: This type involves the cardiovascular, and there are a possibility of suffering heart failure and fluid retention.
Dry Beri-Beri: This type affects the nervous system and can lead to muscle weakness, nerve damage, and paralysis.
Causes of Beri-Beri
Beri-Beri is primarily caused by a lack of thiamine in the diet. This can result from:
Poor Diet: Insufficient intake of thiamine-rich foods, such as whole grains, legumes, nuts, seeds, and pork.
Alcoholism: Chronic alcohol consumption can impede thiamine absorption and storage.
Malabsorption: Any medical condition affecting the gastrointestinal tract’s ability to absorb nutrients; examples include Crohn’s disease or chronic diarrhea.
High Carbohydrate Diet: A diet rich in refined carbohydrates and deficient in thiamine increases susceptibility to Beri-Beri.
Symptoms
The symptoms of wet and dry Beri-Beri differ
Wet Beri-Berri
The patient may suffer from the following symptoms:
Dyspnea
Edema in the lower limbs
Tachycardia
Chest pain
Dry Beri-Beri:
Numbness or tingling in the hands and feet
Muscle weakness
Trouble walking or paralysis
Mental confusion and loss of memory
Prevention and Treatment
Prevention and treatment of Beri-Beri lie in adequate uptake of thiamine :
Diet : Rich foods of thiamine include whole grains, legumes, nuts, seeds, pork, and fortified cereals.
Supplements : Thiamine supplements may be necessary for people at risk of deficiency, people suffering from alcohol use disorders, and malabsorption conditions.
Medical Care: In more serious cases, healthcare providers administer intravenous thiamine injections.
Recovery
The symptoms of Beri-Beri may begin to clear with proper medical treatment. If the condition is left untreated, though, serious complications can occur, such as heart failure and irreversible nerve damage.
Thiamine deficiency must be treated early, and diet should be maintained in order to avoid this disease.
5.Pellagra:
Pellagra is a disease caused by a deficiency in niacin (vitamin B3) or its precursor tryptophan. It can also result from a poor ability to absorb niacin. Pellagra is characterized by the “three Ds”: dermatitis, diarrhea, and dementia. If left untreated, it can be fatal.
Causes of Pellagra
The major causes of pellagra include the following:
Poor Diet: Inadequate intake of foods rich in niacin, which include meat, fish, whole grains, and legumes.
Malabsorption: Conditions affecting nutrient absorption within the gut, such as Crohn’s disease or chronic diarrhea.
Alcoholism: Chronic alcoholism may disrupt the absorption and metabolism of niacin.
Some Medications: Certain medications, such as isoniazid, which is a drug for tuberculosis, may disrupt niacin metabolism.
Symptoms
The symptoms of pellagra can be classified into the “three Ds”:
Dermatitis: A symmetric, pigmented rash on areas of the skin exposed to sunlight, redness, scaling, and cracking of the skin.
Diarrhea: Gastrointestinal disturbances, including diarrhea, nausea, and vomiting.
Dementia: Neurological symptoms such as depression, apathy, headache, memory loss, and confusion.
Besides the “three Ds,” other symptoms include:
Fatigue
Anorexia
Glossitis (inflammation of the tongue)
Cheilosis (cracking at the corners of the mouth)
Prevention and Treatment
Preventing and treating pellagra is all about ensuring adequate intake of niacin:
Diet: Niacin-rich foods should be consumed regularly, such as meat, fish, poultry, whole grains, legumes, nuts, and green leafy vegetables.
Supplements: Supplements of niacin are required for people at a risk of developing deficiency.
Medical Treatment: Treatment of underlying diseases that affect the absorption and metabolism of nutrients.
Recovery
Symptoms of pellagra improve with appropriate treatment in a few days to weeks. Early diagnosis and intervention are crucial in preventing complications and improving outcomes.
