Vomiting in Pregnancy

Pathophysiology of Vomiting in Pregnancy

(1) Hormonal:

(a) Excess of chorionic gonadotropin or higher biological activity of HCG is associated. This is proved by the frequency of vomiting at the peak level of HCG and also the increased association with hydatidiform mole or multiple pregnancy when the HCG titre is very much raised

(b) High serum level of oestrogen

(c) Progesterone excess leading to relaxation of the cardiac sphincter and simultaneous retention of gastric fluids due to impaired gastric motility. Other hormones involved are: thyroxine, prolactin, leptin and adrenocortical hormones.

(2) Psychogenic:

It probably aggravates the nausea once it begins. But neurogenic element sometimes plays a role, as evidenced by its subsidence after shifting the patient from the home surroundings. Conversion disorder, somatization, excess perception of sensations by the mother are the other theories.

(3) Dietetic deficiency:

Probably due to low carbohydrate reserve, as it happens after a night without food.  Deficiency of vitamin B6, vitamin B1 and proteins may be the effects rather than the cause.

(4) Allergic or immunological basis

(5) Decreased gastric motility is found to cause nausea

Whatever may be the cause of initiation of vomiting, it is probably aggravated by the neurogenic element. Unless it is not quickly rectified, features of dehydration and carbohydrate starvation supervene and a vicious cycle of vomiting appears — vomiting → carbohydrate starvation → ketoacidosis → vomiting.[1]

There are no specific morbid anatomical findings. The changes in the various organs as described by Sheehan are the generalized manifestations of starvation and severe malnutrition.

Liver:

Liver enzymes are elevated. There is centrilobular fatty infiltration without necrosis.

Kidneys:

Usually normal with occasional findings of fatty change in the cells of first convoluted tubule,

which may be related to acidosis.

Heart:

A small heart is a constant finding. There may be subendocardial haemorrhage.

Brain:

Small haemorrhages in the hypothalamic region giving the manifestation of Wernicke’s encephalopathy. The lesion may be related to vitamin B1 deficiency.

METABOLIC, BIOCHEMICAL AND CIRCULATORY CHANGES:

The changes are due to the combined effect of dehydration and starvation consequent upon vomiting.

Metabolic:

Inadequate intake of food results in glycogen depletion. For the energy supply, the fat reserve is broken down. Due to low carbohydrate, there is incomplete oxidation of fat and accumulation of ketone bodies in the blood. The acetone is ultimately excreted through the kidneys and in the breath. There is also increase in endogenous tissue protein metabolism resulting in excessive excretion of nonprotein nitrogen in the urine. Water and electrolyte metabolism are seriously affected leading to biochemical and circulatory changes.

Biochemical:

Patients develop acidosis (due to starvation) and alkalosis from loss of hydrochloric acid and hypokalaemia. Loss of water and salts in the vomitus results in fall in plasma sodium, potassium and chlorides. The urinary chloride may be well below the normal 5 g/L or may even be absent. Hepatic dysfunction results in ketosis with rise in blood urea and uric acid. Patient suffers from hypoglycemia, hypoproteinaemia and hypovitaminosis.

Circulatory:

There is haemoconcentration leading to rise in haemoglobin percentage, RBC count and haematocrit values. Slight increase in the white cell count with increase in eosinophils. There is concomitant reduction of extracellular fluid.[1]

Classification of Vomiting in Pregnancy

The vomiting is related to the pregnant state and depending upon the severity, it is classified as:

(i) Simple vomiting of pregnancy or milder type

(ii) Hyperemesis gravidarum or severe type

 1] SIMPLE VOMITING (morning sickness, emesis gravidarum)

SIGN AND SYMPTOMS i.e.:

• The patient complains of nausea and occasional sickness on rising in the morning. Slight vomiting is so common in early pregnancy (about 50%) that it is considered as a symptom of pregnancy. It may, however, occur at other times of the day. The vomitus is small and clear or bile stained.
• It does not produce any impairment of health or restrict the normal activities of the women. Besides this, The feature disappears with or without treatment by 12–14th week of pregnancy.

ETIOLOGICAL FACTOR i.e.:

• High level of serum human chorionic gonadotropin, oestrogen also altered immunological states are considered responsible for initiation of the manifestation, which is probably aggravated especially by the neurogenic factor.

DIETARY MEASURE i.e.:

• Taking of dry toast or biscuit and avoidance of fatty also spicy foods are enough to relieve the symptoms in majority.

TREATMENT i.e.:

• Supplementation with vitamin B1 100 mg daily is helpful. In detail, If the simple measures fail, antiemetic drugs  trifluoperazine (Espazine) 1 mg twice daily is quite effective.
• Promethazine also ondansetron can be used. Furthermore, Patient is advised to take plenty of fluids (2.5 L in 24 hours) and fruit juice.[1]

2] HYPEREMESIS GRAVIDARUM

• It is a severe type of vomiting of pregnancy which has got deleterious effect on the health of mother and/or incapacitates her in day-to-day activities.

EFFECTS i.e.:

• The adverse effects of severe vomiting are e.g. dehydration, metabolic acidosis (from starvation) or alkalosis (from loss of hydrochloric acid), electrolyte imbalance (hypokalemia) and weight loss.[1]

Homeopathic Treatment of Vomiting in Pregnancy

Homeopathy treats the person as a whole. It means that homeopathic treatment focuses on the patient as a person, as well as his pathological condition. The homeopathic medicines selected after a full individualizing examination and case-analysis.

which includes

• The medical history of the patient,
• Physical and mental constitution,
• Family history,
• Presenting symptoms,
• Underlying pathology,
• Possible causative factors etc.

A miasmatic tendency (predisposition/susceptibility) also often taken into account for the treatment of chronic conditions.

What Homoeopathic doctors do?

A homeopathy doctor tries to treat more than just the presenting symptoms. The focus is usually on what caused the disease condition? Why ‘this patient’ is sick ‘this way’?.

The disease diagnosis is important but in homeopathy, the cause of disease not just probed to the level of bacteria and viruses. Other factors like mental, emotional and physical stress that could predispose a person to illness are also looked for. No a days, even modern medicine also considers a large number of diseases as psychosomatic. The correct homeopathy remedy tries to correct this disease predisposition.

The focus is not on curing the disease but to cure the person who is sick, to restore the health. If a disease pathology not very advanced, homeopathy remedies do give a hope for cure but even in incurable cases, the quality of life can be greatly improved with homeopathic medicines.
