The human digestive system comprises of the intestine track and the digestion organs. It involves the diet ad assimilation of food we eat. A healthy digestive system is crucial to the body immune and helps to overcome almost 70% of health conditions. Acne inflammatory and chronic skin condition characterized by pimples in the skin is common in adolescence. It is caused by inflammation of sebaceous glands. The glands produce the oily substance which is stimulated by adrenal glands. Her GP recommends her to take plenty of vegetables and fruits. This is because vegetables supply vitamins A and E and zinc which helps reduce more severe acne and also regulating the hormonal levels. Coca-cola drink is acidic, and excess acid in the body causes acidosis. Acidosis causes fatigue, loss of enthusiasm and other symptoms. Fruits and vegetables help reduce this effect. Tiredness and fatigue experienced by Mrs. Brown could be caused by iron deficiency anemia caused by low red blood cells count. This fatigue can also result from heavy menstrual flow or pregnancy. Eating dark green vegetables and drinking less of acidic drinks can help increase the blood count.BMI below 18.5 is considered underweight. Ms. Brown has a low BMI of 18.5 which is close to being underweight. Her Gp advises her to take a balanced diet. High-calorie food such as fat and regular exercise will help to improve and maintain the BMI in their health range. Bloating is excess gas being dropped in the digestive system. High Coca-Cola intakes may have caused bloating especially when drinking using a straw since the air proceeds the drink. This causes unnecessary stomach discomfort. Women are instructed to have a healthy diet (Gardener 2004) Endocrine systemThe system involves chemical hormones, glands and circulatory of the chemical messengers to targeted organs and homeostatic feedback. The system helps in regulating body functions such as metabolism, growth, sexual functions, sleep, moods and other health functions. Increase in androgen hormone, which rises during adolescence cause growth of oil gland under the skin. The enlarged glands produce more sebum which causes the facial acne. A healthy diet is recommended by the GP, and an active lifestyle helps to regulate the androgen levels. Hypothyroidism is a condition caused by the underactive thyroid gland. This leads to having a low amount of thyroxine hormone which makes one feel fatigued, depressed, aching muscles and dry skin. Medication from the GP helps control the medical condition.Cardiovascular systemThe system involves blood circulation and transportation of metabolic products in and out of the body cells. The proper cardiovascular system is essential for general nourishment, improved immune system, and a homostatic function. Experts say headaches hits when the blood vessel in the skull swell stretching the nerves around them hence causing pain. Inflammation of the blood vessels, blood clot or bleeding in the brain can cause a headache. Disorders in muscles and nerves in the head or neck can lead to the change of chemical activity hence also leading to headaches. The inflammations are caused by dehydration or stress. Caffeinated drinks also cause a headache. Ms. Brown’s GP advises her to take 2 liters of water per day. Taking water helps improve the blood volume level hence proper oxygen circulation in the brain. Regular physical activity improves mental and physical well being which reduces stress. Research shows that Coca-Cola contains 32 mg of caffeine per 200 grams of the drink. Refraining from caffeine helps to reduce a headache.Lymphatic and immune systemThe system is composed of the lymph vessels and the immune system which help fight against foreign antigens. The weak immune system causes one to be susceptible to diseases. Vegetables and fruits help in boosting the immune system. Has major immunological importance (Holt 2008) Part bRespiratory system.The system is composed of the upper respiratory tract; nose, pharynx, sinuses, and lynx. The lower respiratory tract: trachea, lungs, diaphragm, and segments of bronchioles and alveoli .respiratry system involves passage of air through the vessels lung and the breathing muscle. It aids in the circulation of respiratory gases between air and blood.oxygen to the cell is essential for metabolism and nourishment of general health. The system filters breathing air such as dust which may cause allergic conditions. It also defense against disease-causing microbes .the system is also responsible for regulation of homeostatic function by regulating blood ph. This is monitoring carbon (iv)oxide levels.it also help in water regulation by exhaling excess water. Tuberculosis, influenza chronic pulmonary disease asthma among other diseases are conditions caused by dysfunction in the urinary system Urinary system The system consist of renal system (kidney ureter blander urethra ) it helps in elimination of waste products in the body, regulation of blood volume, water, and other body metabolites. It is the drainage system for the excess products in the form of urine. Kidney contains numerous blood vessels and nephrons for the purification of blood. Urine production is involved with health conditions such as diabetes and gout. NMDA receptor has a major role in memory(Kampa 2008) Diagram representation of the urinary and respiratory system Type of diseaseName of diseaseWhy Mr. Ali is at riskEffectsDeficiency – there is lack of certain nutrients and minerals in the body. Degeneration-certain minerals and starts to diminish and organs or tissue loss vitality Infectious diseases- these are diseases which are transmitted from one person to another especially through breath.Osteoporosis TuberculosisHe spends most of his time inoffice hence less exposure to sunlight. This causes a deficiency of vitamin D leading to the disease.Poor diet .Mr. Ali takes fast food which mainly includes fried foods rich in fat content. The food is unbalanced and lacks essential nutrients and minerals such as vitamin d and calcium. Deficiency causes osteoporosis.A sedentary lifestyle since he involves in less physical activity. He uses public transport to work instead of walking and also spends most of the time sitting n the banking hall attending to clients with minimum movementMr. Ali drinks and smokes a lot. Smoking and smoking contribute to the disease.Osteoporosis is also caused by advanced age. As the age progresses, there is calcium degeneration from the bones hence leading to weak bones. Mr. Ali is 65 years of ageThe disease is caused by a bacterium called Mycobacterium tuberculosisIt can be spread from an infected person to a healthy person through a cough, sneezing or inhaling expelled bacteria droplets.Long contact with an infected person can spread the disease. Mr. Ali encounters prolonged connections with people in the banking hall and in using public transport.It can also be spread by being in crowded places where air circulation is poor.Mr. Ali spends his days indoors in packed bank hall. He also uses public means which are also crowded.Tb is also associated with old age. Mr. Ali is 65 years old hence susceptible to contacting the disease.The diseases are also caused by poor dietChronic pain.Reduced life expectancyDisabilityThe bacterial infection causes severe damage to the lungs; this causes severe sneezing and coughing which may be bloody.One also develops breathing problemsIf the infection spreads to the brain, it can cause meningitisType of diseaseName of the diseaseWhy Mr. Ali is at riskEffects.Non-infectious- The disease cannot be transmitted from one person to onother.it can be as a result of unhealthy lifestyle.Tuberculosis Chronic inflammation High blood pressureMr. Ali diet is composed of fast foods which are usually unbalanced and unhealthy. Poor diet causes poor immune system which makes on vulnerable to infectious diseases. His smoking and drinking lifestyle also contribute to poor health. we should stick to low-fat foods(Gross man 1987)It is the body’s natural way of to response germs, toxins stress and other harmful agents in the body.Various lifestyle factors of Mr. Ali can lead to inflammations. These include;Fast foods which are naturally inflammatory and sugary. These include snacks, fried food, luxurious foodStress causes inflammation. Mr, Ali is likely to develop stress due to the long and intense work at the bank dealing with different types of clients.Drinking and Smoking habitsCaused by high blood pressure during pumping of blood in the arteries. This may be due to thin arteries as a result of the accumulation of fat layers on the vessels.Mr. Ali unhealthy habits of taking fast and fatty foods can be a major risk for the infection. He does not also engage in the less physical activity which is dangerous to his health.Mr. A li drinking ad smoking condition can also be a risk of the infection.He lives s a sedentary lifestyle which makes him vulnerable to being overweight.The infection can also cause arthritis it can cause arthritis which is characterized by pain in the jointsDrinking too much alcohol can lead to lead to degeneration of the degeneration of kidney and liver.Long-term effects of high blood pressure can cause coronary diseases, heart failure, stroke, kidney diseases, and dementia.Obesity has roughly the same association with chronic health(Sturm 2002) ReferenceSallis, J.F., Grossman, R.M., Pinski, R.B., Patterson, T.L., and Nader, P.R., 1987.
